Since the very beginning of the war no one in Germany has been allowed to run his own automobile on account of the scarcity of rubber tires and gasoline. All the automobiles displayed in the store windows have tires made of cement. This is just done to make them look better. All the tires have been taken over by the military authorities. No one is allowed to ride a bicycle with rubber tires without a permit. They have invented two kinds of tires for substitutes. One kind is made of little disks of leather joined in the middle, and the other kind is made of coiled wire. Both these tires are advertised, and the advertisements read: "Don't worry, ride your bicycle in war time. Get a leather disk tire; then you don't need a permit." For everything that is scarce in Germany they have a substitute and in this line German ingenuity seems to have no end. They have a substitute for milk called _Milfix_. It is a white powder, and when mixed with water it looks like milk. It can be used in coffee or for cooking. The funny part about _Milfix_ was that when it first came out everybody scorned it, but all of a sudden there was hardly any real milk to be had, and _Milfix_ was put on the _Lebensmittel_ food card, and one could only buy a small quantity of it. Then everybody was just wild to get a little bit of the precious stuff. Then they have egg substitutes. Some brands of it are in powder form and other brands are like yellow capsules. They are very good when mixed with one real egg and make very good omelet. Then there is the meat substitute. It comes in cans and is dark brown in color. It is some kind of a prepared vegetable. It looks like chopped meat and it is said to taste like meat. They have a hundred different varieties of substitutes for coffee, and without any exception all brands of _Kaffee-Ersatz_ are very bad. The most unique thing on the market is the "butter stretcher." That is what they call it. It is a white powder, and they guarantee that when it is mixed with a quarter of a pound of real butter it will stretch it to half a pound. We bought some of it but we never had the courage to try it on a quarter of a pound of real butter; but many boarding-houses used it. Every day something new bobbed up on the market. One of the finest things was _Butter-Brühe_ and _Schmalz-Brühe_. It came in cans the half of which was either butter or lard and the other half was broth. It was fixed this way so it did not come under the butter card or the fat card. The cans weighed a half pound and sold for five marks. It was foreign goods from either Holland or Denmark. Last spring there appeared on the market great quantities of "Irish stew" in cans. The Germans stood around it wondering. What was Irish stew? None of them had the slightest idea. But finally they bought it, for they said, if it was Irish it must be good. They have a substitute for sausage made out of fish. It is awful stuff with a lingering taste that lasts for days.
