ntestine, and no doubt predispose to cancer. It is pretty well
established at the present time that cancer is a disease of meat eating
men and animals. About one cow in fifty has cancer, whereas every
seventh dog taken to a hospital sick is found to have cancer. Dr. Mayo
recently gathered some statistics on this matter, and he told me and
some other doctors that dogs under eight years of age, every fourth one
has cancer; every third one of dogs ten years of age has cancer, and
half of all the dogs over twelve years of age have cancer and would die
of it if left to themselves. These statements were based on laboratory
animals that were killed when they were well and not sick, so the
observation ought to be fairly reliable.

I was to say particularly a few words about the soy bean. I am not going
to try to tell you very much about it, because I do not know very much
about it. If you want to learn all about it, you can easily do so by
writing to Mr. W. J. Morse, of the Bureau of Plant Industry, U. S.
Department of Agriculture, Washington, D. C. Farmers' Bulletin 973, one
of the very best on this subject, tells all about the culture of this
exceedingly useful legume. The soy bean is really the beefsteak of China
and Japan. In those oriental countries, soy beans have been used for
centuries. It is more nearly like a nut than a bean. Perhaps I better
show you the pictures first, and then have the curtains raised so we can
get a better inspection of the beans.

The composition of the soy bean is very remarkably different from that
of the ordinary bean. It contains forty per cent of fat, on the average
and about forty per cent of protein--sometimes more than forty per cent.
The protein is sixty per cent more than in our best ordinary foods; and
the fat is five or six times as much as that found in the ordinary bean.

A thousand different varieties of the soy bean have been gathered by the
Bureau of Plant Industry of the Department of Agriculture at Washington.
Five hundred of these varieties have been tested, and thirty or forty of
them have been found to be adapted to this country, and very useful. You
can see in this picture the great mass of pods to be found growing on
the plant. This slide shows how unusually well they grow in the field.
You can see the pods scattered all through the plant. A large part of
the foliage is made up of pods. This is one of our own fields of the
beans that we raised this year. It is rather diff
