thing -- anything to see you. It will be a wonderful trial of patience to wait until summer but will have to, I guess. ...... I stop and assure myself it is all true. Yes –- all true. We love each other, and what could be more wonderful.

[[underlined]]To Willie, January 4, 1925[[/underlined]]: I am so glad that your father liked me and here's what Mother wrote me about you: "my heart is all one prayer, dear, for you and Willie, [[underlined]]my[[/underlined]] daughter some day, I trust. I hope that she can love me. It will be very easy for me to love her." And in speaking of the lovely flowers you sent her she said: "Someway they seemed just like [[underlined]]her[[/underline]], the lovely budding summer, and the shy, white sweetness of spring."

[[underlined]]To Willie, January 9, 1925[[/underlined]]: You asked me to tell you all about my work. I have wished many times during the past few days that I might consult with you about varios chemical questions that have come up, for I know that you could have helped me. But, at any rate, my job for a few weeks is to thoroughly familiarize myself with this new process, which is, as I told you, a method of copper brazing in an atmosphere of pure hydrogen. I want to learn this thing to the motion of the last electron if I can. At least that is my goal while I am studying it. The process, very briefly, is this: for example, we shall braze two pieces of steel together.

A is one piece of steel, and is set in the slot in the steel block B. A piece of copper wire is wound around the joint between A and B as shown. The whole business is then put into a furnace containing pure hydrogen, and heated to about 1,100°C. The heating is done by ribbon resistors, which are merely steel ribbons heated to incandescence by an electric current. The copper wire melts at 1083° C and the liquid copper flows into the joint between the two pieces of steel and seems to draw the grains of the steel up into it, uniting them with each other. The work is then slowly cooled again to normal temperature, remaining in the furnace surrounded by hydrogen. When it is cool,
it is removed and the two pieces of steel are found to be as strong as if they were one solid piece. In fact, the brazed joint is even stronger than the steel itself. The purpose of the hydrogen is to prevent oxidation while the process goes on. My job is going to be to help adapt this process to the manufacture of some of the other products of the Company. The process possesses very great economies over various other methods of accomplishing the same result. It is so new though, that it hasn't been adapted yet. So I expect to learn a lot, and have a chance
