By the time he returned, I had the feed-pipe of the carburetor all off (I know that these names mean nothing to you, but they will to Daddy), and the two mechanics which he had found would not, of course, believe a simple woman--and I guess that I looked more simple than I felt even by this time, for they had thoughtfully begun to clean the streets while I was exploring under the car, and I was not only muddy but wet. After a heated discussion in Anglo-French, the men believed me, and stopped cranking, and, on turning the pipe down to let the gas run out, we were delighted to see pure aqua pura run out--not gas at all! Now, don't you call that the limit? The last bidon of gas which I had put in wasn't gas at all--it was water, pure and simple. Of course, we had to wash out the tank, waste quarts of essence, which is more precious than gold these days, and then clean out the feed-pipe and carburetor. You never saw such a job, and all performed on the street! All told, that little drink of water which I gave the Ford cost about one and a half hours of time, and about sixteen francs in money. We got under way again, but it was so late that nice Mrs. Jackson had to rearrange all her plans. However, we got a great deal done, and, incidentally, I had a wonderful day being with her. We lunched at a queer little restaurant over in Montmartre--had hors d'oeuvres, cheese omelette, lots of very good bread (at least, as bread goes these days; how I shall enjoy some toast made out of white bread!), and cream cheese and apple sauce, with coffee which was the real article--not chicory or burnt almonds, or whatever it is that they give you at half the places. We talked about everything under heaven and earth, and I came away from luncheon more than ever convinced that she is a wonder. She asked me to go South with her the 22d of this month, but I am not going to. First place, the work needs me, and second place, I do not want to take my vacation until this summer, and then take it all in one big lump, doing something worth while. I am awfully complimented that she asked me, anyway.
