From this experiment it is evident that the individuality 

 of the lupine results from the different character of the seed 

 coats of the different seeds as regards the permeability. 



This will offer an explanation for peculiarities later to 

 be discussed. 



Least Amount of Water necessary for Germination. 



From Experiments 1 & 2 we learn that corn is capable of 

 absorbing forty nine to fifty nine per cent of water in sixty 

 hours. In this experiment it was my object to determine the 

 least amount of water necessary for germination. 



The desired end was sought by experiment in the following 

 manner:- Seeds of each kind, and of known dry weights were place 

 in distilled water of the temperature of the laboratory at 

 intervals such that when removed from the water they had soak- 

 ed 0,1,2, 10 hours. Of the corn - Perry's Golden Eagle - 



and the peas - Large White Marrowfat - ten seeds were used in 

 each of eleven sets,. 



As soon as the seeds were taken from the water they were 

 wiped dry, weighed, and placed in a germinator made as follows;- 

 A four quart granite-ware pan containing one quart of water 

 had a piece of cheese cloth stretched over the top and firmly 

 held by a wire band just below the rim of the pan. Upon this 

 stretched cloth were strips of tin, one half inch wide, stand- 

 ing on edge and bent so as to form one inch squares into which
