  To the Science Congress of the Tenth Anniversary Congress of the National Council of American-Soviet Friendship:

  It is a matter of deep regret to me that the distance from Pasadena to New York and the difficulties of present-day travel prevent me from speaking before the Science Congress on the subject of Soviet chemistry. I send to the Congress of American-Soviet Friendship this expression of my sincere hope that the Science Congress will represent only a first strand, even though an important one, in the ultimate cable linking science and medicine in the Soviet Union with the fields in the United States. The need for cooperation between the U.S.A. and the U.S.S.R. is as great in chemistry as in other sciences. We know from the limited information which has reached us that the work in chemistry carried on in the past few years in the Soviet Union, is characterized by the same untrammelled spirit of bold, imaginative exploration of the unknown which has evoked the recent American discoveries in chemistry, and we can be assured that great and rapid progress could be made by the whole-hearted, open cooperation of the scientists of the two countries. Let us look forward to a future when American scientists, in large numbers, are lecturing and working in Soviet laboratories, American students are studying in Soviet universities, and Soviet scientists and students are in America in equal numbers, carrying the most inspired teachings of each country to the other.

  Nov. 5, 1943

  Dear Mom,

  The box of food is wonderful. You are certainly an expert sandwich-maker. I have only been able to eat approximately one half of the stuff.

  We are in old tourist-class Pullmans. They are the dirtiest things imaginable. There are exactly one hundred air cadets occupying three cars. We were hitched to the California Limited until Callup, New Mexico. I haven't' found the name of this train yet. It is better than the Limited though.

  I was amazed by the number of yellow and blue diesel-electric freight locomotives Santa Fe has. The[y] are all over the place.

  Arizona is a beautiful place. New Mexico and Texas so far haven't impressed me. Perhaps Texas will be better farther east.

  I failed to get the fire place fixed before leaving. Perhaps that bit of broken pipe can be unscrewed by inserting some wedge shaped instrument.

  Give my love to the kids.

  Love,

  Linus

  P.S. I'm still attacking the food.

  Nov. 7, 1943

  Dear Mom, Pop, Pete, Linda, and Crellie,

  How are you all? My address is:

  Pvt. Linus Pauling Jr.

  A.S.N. 39711550

  Bks. 295, Trg Sg. 32

  Group 308 [crossed out in ink, letter written in pencil]

  Sheppard Field,

  Texas

  This place is pretty foul. The water is almost unbearable. It has a high salt content. Sheppard Field is tremendous about 125,000 men. I think, and water had to be piped from a lake that had been polluted by salt water from oil wells. A strong cold wind blows continually, and dust is everywhere.

  We got our uniforms on Saturday. Life is very confused, and hanging over everyone is the ever present fear of washing out. Apparently a good half of the cadets will wash out, because they need gunners, as we all have to remain in the air crew. I am worried about my eyes.

  I am down to the last orange food that Mom fixed for me. It was really good. The army food here is rather good. The horrible water spoils everything it touches. The coffee is bad, but tea covers up the water taste well. As a result I drink tea at all meals.

  I have no pen, so please excuse the pencil.

  I'll be around this place a month; perhaps longer. There is a shortage of noncoms that know anything. Our C.O. is a private that has been here seven weeks. Everything shifts around so much that one can be sure of nothing.

  I think I will not be able to get home for a long time; probably a year or more. One is allowed to go only 150 miles on a three day pass, and these are very uncommon. After two weeks we will start getting Saturday night passes. Meanwhile I try to get adjusted to this army life.

  The PX helps to make life easier. The have reading matter, and soft drinks, and ice cream. Even the coke tastes of salt.

  Give my regards to Sadie and Jerry.

  I shall be glad to hear from you.

  Love,

  Linus

  November 13, 1943

  Dr. G. V. Caesar

  Stein-Hall and Company

  285 Madison Avenue

  New York, New York

  Dear Dr. Caesar:

  I thank you for your chart of the nitration of cellulose by nitrogen pentoxide, which I return herewith.

  I do not think that the linear relation between logarithm of percent nitrogen and logarithm of nitration time has any significance. I would interpret the data in the following way. If each hydroxyl group of the cellulose were to be nitrated independently of the other, the percent of nitrogen would approach the limiting value 14.14 according to the exponential function derived from the first order reaction rate theory; that is, it would reach the halfway point, 7.07 percent, in a given time, the three-quarters point in twice that time, the seven-eighths point in three times that time, and so on. Your data indicate that the reaction deviates from this by slowing down with the passage of time. This presumably means that as some hydroxyl groups are nitrated the remaining ones become more difficult to nitrate.

  A possible explanation of the practical independence of the rate of nitration of the N₂O₅ concentration is that a relatively small amount of N₂O₅ is needed to form complexes with the hydroxyl groups, and that the reaction of nitration is then essentially a unimolecular rearrangement within these complexes; under these circumstances the rate of the reaction would be independent of the N₂O₅ concentration so long as enough N₂O₅ were present to keep nearly all of the hydroxyl group combined.

  Sincerely yours,

  Linus Pauling

  Dear Mom,

  I am glad to hear that you are working. It will be an interesting experience for you to work in some place such as Tech. Be sure you don't overwork yourself doing two jobs at once, though

  Life here is becoming more enjoyable day by day. My sense of humor is recovering, my health is improving, and my adjustment to army life is progressing favorably.

  We arrived in Wichita Falls about 6 P.M. Friday. On Saturday, the 6^th we got uniforms and our first shots, 1 in each arm, tetanus, and typhoid. The tetanus hurt badly for fifteen minutes; the other started several hours later and made the arm almost unusable for a day or two. Last Wednesday or Thursday we had another set; smallpox and another typhoid shot in the arms. This was really a large typhoid injection; it raised a fever and made me pretty sick for a few days. Now I have a head cold, but otherwise things are progressing very well.

  We've had a score of mental tests, and more to come. I haven't found my grades in them yet. I'm especially interested in my score on the Army General Classification Test; it determines whether one goes to O.C.S. or not. It wont' affect my cadet status, but if I wash out I may be able to go. We also had a test to determine which of three things we could be if we wash out: radio-gunner, air mechanic-gunner, or armorer-gunner. I messed up the radio test no aptitude, so I chase the armorer job. It will get in into action most quickly, three months or so. With luck, however, I wont' wash out.

  By the way, I should tell you the cadet schedule. It is this, with leeway of two or three months both ways:

  Private Basic training, one month or so.

  College training three or four months.

  Cadet Pre-flight, probably at Santa Ana, one or two months.

  Flight training, eight or nine months.

  I was glad to hear about my cousin. We take the test that determines whether we will be pilot, navigator, or bombardier here instead of after college as was the practice. Next week I will probably be able to tell you the results.

  Much love,

  Linus

  Dear Dr. Geissman:

  I do not know a great deal about the practical methods of measuring the lipoid level in the fractionating column as suggested in your letter of November 10, but I think that a technique might be developed along the lines which you indicate. The magnetic susceptibility of liquid oxygen at -200º C. is about 300 x 10-8 (volume susceptibility), and that of the gas is about one thousandth of this, so that the difference is significant. The values for liquid air are about one-fifth as great. I suppose that if the fractionating columns are made of steel the magnetic method would not be easily applicable. Otherwise, it might be useful, and I suggest that you talk it over with some one in your Physics Department. If you want to send me a detailed description of the fractionating column, I would be glad to look into the matter further.

  Sincerely yours,

  Linus Pauling

  November 18, 1943

  Dear Mom,

  I was very glad to get yours and Daddy's letters. I was very pleased with Pete's and Crellie's that I received today.

  I need socks more than anything else. I take size 10 . The army gave me 7 D shoes. They are plenty big. We have both khaki and grey-white socks.

  I am flat broke, but that is not much hardship provided I don't want to go to town or buy something at the PX. We are due some travel pay, but God knows when the army will get around to distributing it.

  I am not in need of underwear yet. I do need handkerchiefs, the cheaper the better. They should be white. They get used as washcloths, napkins, dust rags, shoe polishers, and then I blow my nose. Some fun.

  If it is too much trouble to mail my ration books to the O.P.A. in Pasadena, send them here and I'll mail them.

  If it is not at all possible please send me a shoe stamp. I think that will constitute my first major outlay of money.

  I am enclosing the key to my overnight bag. Some of the clothes in it are dirty, I'm afraid.

  I'll have to spend more time thinking about Christmas.

  The training schedule has changed since Rich was through.

  Forgive the writing. I'm trying to finish before the nine o'clock lights-out.

  Much love,

  Linus

  November 20, 1943

  Dear Mom, Pop, Pete, Lin, and Crellie,

  How is California? This Texas climate is really something. The afternoon and evening are nice and warm, but in the early morning it gets very cold. As a result everyone has a continual cold.

  We got passes this weekend, and most of the fellow went into town. I haven't gone in yet, but I will just as soon as I get some money. The latest latrine rumor is that we get travel pay tomorrow.

  I have discovered some things that I need. First a silver or gold dog tag chain, nice and thin, but masculine, and about twenty-six inches (very approximate) in length. It is arranged like this, presumably so that the tags swill not act as a bell in enemy territory: The tags are about two inches long.

  Second, don't we have a little iron around somewhere? I could certainly use one, and it would be a source of profit. Suntans, especially, have to be ironed extremely often. We won't wear Suntans until summer unless we go to some place like California or Florida.

  Other things, such as a fancy hat, shoes, and pants that match my blouse, I had better buy myself when I become solvent. The first payday comes between the 1^st and 15^th of December.

  Tell me how the garden is getting along. How does our new front walk look? Linda should keep me informed on her Scout activities.

  I'll get no pass on Thanksgiving. There's a good chance of a three day pass on Christmas, though.

  I wish the powers-that-be would hurry up and give us the rest of the tests. I'd like to know what is coming off. By the way, I'm sending a clipping I mentioned in the last-setter instead of the whole paper, because I couldn't get a two cent stamp. Also this is the last airmail letter until I get paid.

  Give my regards to Sadie and Jerry.

  It's probably about time Pete washed the car. That should be a job of the oldest of the offspring available.

  Be good.

  My love to you all,

  Linus

  Thursday afternoon

  Dearest little love:

  I am on the slow train through Arkansas today! I wish that it were going West- then I'd have something to be thankful for. We were held up for three hours by a wreck last night (to a freight train, not to us), and have been jogging along leisurely since then- now about four hours later- which means Washington at about 8⁰⁰ tonight: this shows that from now on I'll have to allow a little leeway in traveling. I've already become so tired of riding that I do nothing but sit (and think pleasant things about you- I'll explain (or rather, demonstrate) when I see you next Tuesday; this morning I jumped out of my berth, dressed, washed my face and combed my hair, and went to breakfast fast, without shaving, the steward having called out "Last call", even at 9 o'clock; and I haven't had enough energy since then to shave. If you were here I'd scratch you.

  We are just going through a little town- West Newton, [Tenna]- the train goes right between the houses and stores on Main Street. This is the B&O. I can't lie down today, because a mistake was made in my ticket- I haven't a roomette (there are none on the train), but fortunately a lower berth was free.

  The Chief reached Chicago safely (late) and I rode in a coach seat to Madison (no first-class seats were available). Mrs Williams made a nice fried-egg breakfast for me- their guest bed is the usual sort, but not so lumpy as usual, and I slept well. I've been sleeping well- until 11:30 on the Chief Tuesday, from about 9! I went over Williams work, and had lunch with him and F. Daniels, who has a wonderful set of hand-tinted photographic portraits of his wife and four children in his office. I'd like to see Mrs. D.- Farrington is a nice little fellow.

  The train back to Chicago- the famous "400" flyer- was an hour and a half late on a 2 ½ hour run (the diesel locomotive had broken down), but I had time enough to catch this slow Washington train.

  I notice that the air cadet across the aisle has a little OD canvas bag, with zipper; [drawing of bag] it is about 7" x 8" x 18".

  I've been thinking about a possible theoretical interpretation of some data in a paper in last month OACS- I haven't any good new ideas about war work on this trip yet.

  You are a wonderful girl, darling, the best in the world. I've been looking forward to getting back to you ever since leaving. The time will be half gone in 13 hours (it is 2 now- 11 AM in Pasadena), and from then on I'll be coasting over the hill to you. This trip is a boring one; I hope that my presentation of our work at the meeting tomorrow is good.

  We have just passed long rows of hundreds of old beehive ovens, in which coke was made; one of the ovens is occupied by a tenant, an old man.

  Eat well, don't work to hard, build up your strength for the reunion next Tuesday with

  Your adoring

  Paddy

  Love to Linda, Crellie, Peter.

  Saturday morning, at Sterling's

  Dearest little love:

  I adore you, dear sweetheart. Your card was here when I arrived and I got your letter from Dr. Richards last night. You are the sweetest thing in the whole world. I'm glad to be starting home today.

  I reached Sterling and Edith's at 9³⁰ last night- my B&O train was four hours late, having been held up by the wreck in Ohio. Our meeting yesterday went off well, but Kisty was not there. My report was well received- the Army and Navy people gave the work high priority, and then $100000 was appropriated for it for the next six months- more than I had asked for, since the army has asked us to do some more work for them, and the Hercules people pointed out that we need and should build a surveillance room in the Canyon. Then at 5³⁰ I went to see Dr Richards, and had a good talk with him. He wants us to work on bacillary dysentery, and perhaps later on penicillin (he say pen'icill'in). I called Miet, and shall see him at noon today.

  I hope you aren't having too much trouble sleeping. Don't worry, dear heart- remember that I adore you. Save up your strength for Tuesday.
