DIFFERENT PARTS OF A TREE.

there is some difference in the influence of the sun, 

 for we find that some kinds, as the Gooseberry, ripen 

 best in the shade, and some in the sun ; this must be 

 learned by the practitioner by observation of the 

 ripening of different kinds in different locations of 

 of heat, cold, drought, and moisture,

REMARKS ON THE DIFFERENT PARTS OF A TREE, 



Art. 1. — On the Seed, 



The seed contains all the rudiments of a young 

 plant in embryo, and commences a state of vegeta- 

 tion so soon as a proper heat, air, and moisture is 

 present, when, imbedded into a congenial soil, if 

 its vegetative properties have not been damaged or 

 lost by any accidental causes which might have 

 happened. It is seldom seen that seed loses its 

 vegetative properties by cold, when a free circula- 

 tion of air is present, and it is not saturated by 

 moisture. In order to prove this fact I have ex- 

 posed many kinds of seed to extreme cold, but I 

 have never found them to be injured if in a dry state ; 

 but on the contrary, when seed is kept in a warm moist 

 situation its vegetative principle is often put into ac- 

 tion before its proper season, and the consequence 

 is, the seed is materially injured, if not totally de- 

 stroyed. Many kinds of seeds covered with a hard 

 shell, as stone fruit, keep better and vegetate more 

 freely in the spring if they are mixed with earth
