 furrounds the firft joint of the ftem within the earth, a circular fet

 (hoot their roots into the earth ; and in this manner many items are 

 produced in the fpring from one feed fowed in the autumn preced-

 and of ripening its feeds, may be performed in one fummer even in 



this northern climate. 



Another peculiarity attends the growth of wheat and other graffes; 



the leaf, which furrounds and ftrengthens the ftem by its foot-ftalk, 

 depofits at every lower joint a faccharine matter for the purpofe of 

 nourifliing the afcending part of the young ftem ; and in the upper-

Owing to this fecretion of faccharine matter at the foot-ftalk of 



every leaf, and its colkaion round the joints of graffes, it happens
