10 NUT GROWING 



brooke with natural trout food. Taking into con- 

 sideration the known breeding habits of Gammarw 

 pulex, a part of the problem could be reduced to 

 figures. It was found mathematically after the man- 

 ner of population statisticians that at the end of 

 three years or so the progeny from one thousand 

 shrimps would fill the bed of the stream completely 

 and oblige the water to run out upon the bank in 

 order to get around them. Four thousand shrimps 

 were ordered and the trout now have to be lively in 

 order to get their share of unearned increment away 

 from other fish and from the larvae of helgramites, 

 dragon flies and the ephemeridse. 



Population estimates which do not take into ac- 

 count the apsedion* index in its relation to cultural 

 limitations of man and of his domesticated animals 

 will be as misleading for us as they presumably were 

 for the sociologists of Rome, Greece and Egypt. 



Biologists and chicken breeders have their own 

 views concerning the fall of Rome. 



Japan appears to be crowded because of agricul- 

 tural thought-habit. Japanese chestnuts, heartnuts 

 and pine nuts would furnish a better balanced food 

 iration and at less cost than the customary food 

 ration now belonging in the rice category. Phys- 

 ical strength of the people would be increased in the 

 course of a single generation on a nut diet. North 

 American nut trees and nut bearing annual plants 

 would thrive in Japan, furnishing a luxurious range 

 in qualities of food beside supporting a population
