 Hence, he, who would most successfully cultivate 

 them, must know something of Geology, a vast and ex- 

 ceedingly interesting field of inquiry, as yet but imper- 

 fectly explored, and the importance of which to agri- 

 culture and arboriculture is but beginning to be prop- 

 erly appreciated. To know the kind of plant which 

 can be most profitably cultivated on a given soil, is 

 one thing ; but to prepare a soil for the best culture 

 of a given kind of plant, demands other and much 

 more complicated considerations. Indeed two of the 

 chief points in the gardener's art consist in the ac- 

 commodation of the soil to the nature of the plant, 

 and in teaching the plant to accommodate itself to 

 the soil and climate. 



So numerous and intimate are the reciprocal rela- 

 tions between the Animal and the Vegetable kingdom, 

 that no one of them can be thoroughly understood 

 without a pretty full acquaintance with the other. 

 Hence, a knowledge of Zoology, Ornithology, and 

 Entomology must prove of high utility to the garden- 

 er ; enabling him to distinguish those quadrupeds, 

 birds, and insects, which are friendly, from those 

 which are inimical to his interests ; for it is only by 

 accurately discriminating their kinds, and by study- 

 ing their natures and habits, that he can avail himself 

 of the services of one, or protect himself from the 

 depredations of the other. 



There is no one class, in whose success the inter- 

 ests of mankind are so much involved, as in that of 

 the cultivators of the soil. By this I mean, that, as
