In the last column are given the number of pounds 

 necessary to completely sow an acre with average commercial 

 seed. The figures are based on the quantities of seeds 

 sown in the mixtures commonly used in the country, from 

 which it is found that from five millions to ten millions living 

 seeds are sown per acre. For instance the following are 

 typical mixtures, one of Canterbury fields and one of Auck- 

 land bush burns. 



TABLE III. 



In the last column of Table II. then, the calculations 

 are based on the assumption that five millions of the large 

 seeds up to 12 millions of the smallest are necessary to sow 

 an acre. The smaller seeds are more easily buried, or their 

 tiny plants more easily destroyed, and thus in practice greater 

 quantities of these seeds are sown than their number to the 

 pound would necessitate. Since these seeds are never sown 

 pure, and since conditions veiry immensely, the figures in 

 the last column are to be taken merely as an indication that 

 in general the quantities of different seeds required for an 

 acre vary greatly, and that certain seeds are much more 

 economical in use than others are.
