One more illustration, as showing the re- 

 markable diversity of the investigations in 

 these days of the New Earth, must suffice. 

 Certain portions of California, notably within 

 a radius of a hundred miles from San Fran- 

 cisco, seem peculiarly adapted to the produc- 

 tion of eggs and chickens, particularly the for- 

 mer. Near the town of Petaluma, the center 

 of what is said to be the largest poultry region

 poultry foods for the production of flesh, fat, 

 eggs and feathers, investigate questions of 

 sanitation, and, in general, give scientific and

 This is a serious matter in Europe, and, though 

 not so prevalent in the United States, the dis-
