Our friendship became undying when Monsieur found out that we were the solution of his financial pinches. He came up one night, and, hooking his thumbs in his purple suspenders, asked for a loan of "shong shanquante francs shusqua sheudi." Jeudi never came. To Sempé's intense relief, we agreed to take out the debt in groceries. This was the beginning of a sort of gentlemen's agreement. A paper, thumb-tacked to a shelf in the shop, kept the record of our transactions. When I came to make purchases in the morning or when Herbert dropped in of an evening to buy a supplement to our dinner for unexpected guests or our own good appetites, we could see at a glance whether to pay cash for what we bought or whether we should do a sum in subtraction. It was generally subtraction, and Sempé, wagging his head, would say, "This goes well—soon I shall be square with you." But the satisfaction of being square with the world was never Sempé's for long. The arrival of a barrel of wine or a load of potatoes would send him running up the stairs for the money to help finance his business. In spite of our slender resources we did not feel this to be a hardship. Not infrequently it was an advantage. First of all things one has to eat. We always began to get our money back immediately in the necessities of life. Instead of having our money out in an uncertain loan we took the attitude that our board was paid for two or three weeks in advance.

In another connection, we had the benefit of the advantageous side of the Golden Rule.

In our study of Turkish history we had constant use of Von Hammer's Histoire de l'Empire Ottoman. This meant much transcribing by long-hand at the Bibliothèque Nationale where the typewriter could not be used. If only we had Von Hammer at home! But it was a rare book—eighteen volumes and an atlas—far beyond our means. One day we were browsing at Welter's, the most wonderful bookshop in Paris, on the Rue Bernard-Palissy off the Rue de Rennes near Saint-Germain-des-Près. Monsieur Welter, who took pains to become acquainted with and discover the specialty of every passing client, told us that he had a set of Von Hammer, recently purchased at a London auction. He sent a boy to bring it out. Oh how tempting it looked, beautifully bound in calf! We handled it fondly, but turned regretfully away when he said that the price was two hundred francs.

"Do you not want it?" asked Monsieur Welter, astonished. "It is indispensable for your work and you do not get a chance often to purchase a set of Von Hammer. Never will you find it cheaper than this."

"I do want it, and it isn't the price. I'll come back later, hoping you will not have sold it."

We each had a volume in our hands. I poked my nose between the pages of mine to sniff the delightful odor to be found only in old books. Monsieur looked at us, smiled, and said, "You mean that you haven't the money. You will have it some day. No hurry. Give me your address and the books will be sent around this afternoon."

The delightful relationship thus began lasted until August, 1914, when Welter (who never became naturalized although his sons were in the French army) had to flee to escape internment. His business was sequestrated. German though he was, we never cease to mourn the only expert bookman in Paris. We have tried a dozen since, some of them charming men, but none with the slightest idea of how to sell books. Welter had book-buyers all over the world. Whenever he came across rare books in your line, he mailed them to you with the bill. If you did not want them, you sent them back. Every three months, a statement of the quarter's purchases came, and you sent a check when you had the money. One's attention was brought to many valuable sources, and one was able to buy books of immense value, the possibility of whose acquisition one had never dreamed of.

Monsieur Welter told me years later, when I recalled the Von Hammer incident, that he didn't lose five hundred francs a year in bad bills. "The dealer in old books who does not give all the credit the buyers need is crazy," he said. "What man interested in the things I deal in would think of cheating me? Your husband wanted Von Hammer. I saw that. Any man who wanted Von Hammer would pay for it in time."

We had never had a French book-seller offer us credit, much less send books on approval when we had not ordered them.

When I think of the hundreds and hundreds of books we bought from Welter, I realize one of the secrets of the inferiority of the French to the Germans in business. The French cannot bring themselves to give credit: they have an innate fear of being cheated, and understand commercial transactions only in terms of cash. For years I have made a point of watching French shopkeepers. Invariably they arrange that the money is in their hands before they give you your package.
