THE PEOGBESS OF SCIENCE.

but also opens an opportunity for 

 valuable scientific investigation. Dis- 

 section in the laboratory and histo- 

 logical examination can not tell us all 

 that we need to know about animals. 

 This we can easily realize if we con- 

 sider what our knowledge of man I 

 would be if it were confined to the re- 1 

 suits of the dissecting room. Our 

 bureau of fisheries is in many ways 

 setting an example to other nations, but 

 we shall probably find that in the near 

 future Japan will surpass us and every 

 other nation in the intensive breeding 



1S74 the number reached fifty, and in 

 the following year breeding was begun. 

 Over one hundred young were hatched 

 the first year, but nearly all of them 

 were devoured by their parents. It 

 thus became necessary to have separate 

 ponds for the young of the first year 

 and of the second year, while those 

 of the third, fourth and fifth years 

 might be mixed. Last year the farm 

 raised about 70,000 turtles, and it is 

 expected that about 60,000 of them will 

 be reared. When three years old, they 

 are sold in the markets of Tokyo for

and rearing of animals living in the 

 water. Indeed, in some ways they ap- 

 pear already to have accomplished this. 

 For example, there are complaints of 

 the disappearance of the diamond-back 

 terrapin, but apparently no efforts are 

 made to rear it. In Japan the soft- 

 shelled turtle is reared and sold in 

 large numbers. The accompanying il- 

 lustration shows the turtle farm of the 

 Hattori family, near Tokyo. In 1SGG 

 the first large turtle was caught; by 



a price in the neighborhood of forty 

 cents each. 



Goldfish have for a long time been 

 bred in Japan, being perhaps the most 

 characteristic oriental fish. The ac- 

 companying illustration shows some of 

 the types raised, as depicted by Japa- 

 nese artists. The extreme plasticity 

 of this fish and the types that are 

 developed by selection are of very 

 considerable scientific interest and 

 would doubtless serve well for the
