This mixture would give the enormous number of 

 over 54,000,000 seeds ! In an acre there are 6,272,640 

 inches, so that the mixture would give about eight seeds

 and leaves a large margin for worthless seeds, for im- 

 perfect sowing, and for destruction of plants by insects 

 and frost. 



The weight of the seeds of each of the species of the 

 above mixture, together with the period of blossoming 

 of each, ■w^ill furnish a sufficient reason for the quantity 

 recommended, and the reader is referred to Table XIV. 

 for further explanation. 



A permanent pasture mixture, recommended by the 

 Messrs. Lawson & Sons, very experienced seedsmen of

 given in the first chapter. It ia as follows :
