EXPERIMENTS ON THE GROWTH OF BEANS. 



361 



Dry substance of the bean plants in grammes. 



These numbers completely confirm the conclusions drawn from 

 the weight of the seeds alone. If the crop from the pure turf be 

 taken as unity, the weights of the entire crops bear the following 

 proportions 



1:5-7: 7'7 : 10-9 



or if the weight of the crop in the \ saturated turf be called 2, and 

 that of the and fully saturated turf be compared with it, the fol- 

 lowing proportions are found 



2:2-7: 3'8 



If the weight of the crop furnished by the pure turf be sub- 

 tracted from each of the others, and the weight of the crop in the 

 \ saturated turf be taken at 2, then the crops in the \ and fully 

 saturated turfs bear the following proportions to it 



2 : 2-8 : 4'2

SECTION I. 



SOIL AND MANUEING. 



The Japanese empire stretches from the 30th to the 45th de- 

 gree of north latitude. The average temperature and distribution 

 of heat constitute a climate embracing all the gradations between 

 those of central Germany and of Upper Italy. A solitary tropical 

 palm, not fully developed, grows by the side of the northern pine,
