St. Michaels Island.— In St. Michaels Island we have a 
somewhat different condition. Large numbers of cattle and 
sheep are kept on the island, but they belong to the landlords, 
who export most of the meats and milk products. The peasants 
who take care of the stock and market the products toward pay¬ 
ment of rent for the land, principally use the ass as a beast of 
burden and a milk producer for his own family, because this 
animal can be kept more economically. Notwithstanding the 
fact that the climate is not favorable for tuberculous people, the 
disease is very rarely seen among the peasants. 
Iceland. —A very similar condition exists in Iceland, yet the 
Icelanders are quite susceptible to the disease when they emi- 
o-rate to Denmark, where meat and milk are staple articles of 
food. 
Switzerland. —In some of the cantons of Switzerland there 
are few cattle, goats being largely used instead, and tubercu¬ 
losis is not common in man, while in other cantons there are 
more cattle, and tuberculosis is more prevalent among the 
people. 
Italy. —In Italy, a country blessed with one of the balmiest 
climates of the globe, tuberculosis is very prevalent. 
Steppes of Russia. —The Cossacks who inhabit the steppes 
of Russia are free from tuberculosis. These people use the 
flesh and milk of the horse for food. They have large numbers 
of horses, but no cattle. 
Great Kabylia. —Tuberculosis is unknown among the semi- 
civilized tribes of Great Kabylia. These people have large 
flocks of sheep and goats, but no cattle. 
South America. —Similar conditions are found in a majority 
of the South American countries. That is, they do not use 
much beef or milk, and they are comparatively fiee fioin tuber- 
culosis. 
The United States. —But let us come a little nearer home. 
A few years ago when the red man followed the bison and the 
deer trails over our western prairms unmolested by the hand of 
civilization, Minnesota and Iowa were thought to be nature’s
