24 GENERAL REMARKS. 



of different dimensions. The last line, for instance, snows 

 that, if forty-eight trees be planted on an acre, each thirty 

 feet apart, there may be forty-eight beds of thirty feet square, 

 or thirty beds of forty-eight feet square, formed from the 

 same quantity of land. An allowance of about .one-eighth 

 must, however, be made from the above calculation for walks 

 and paths. 



The table may also serve to show the gardener how to 

 dispose of any given quantity of manure, that may be allotted 

 for an acre of ground. If, for instance, it requires three 

 hundred and two trees to plant an acre when placed twelve 

 feet from each other, it will require as many heaps of manure 

 to cover the same quantity of ground, if dropped the same 

 distance apart. It therefore follows, that if one hundred 

 loads be allowed to the acre, each load must be divided into 

 three heaps. If seventy-five loads only be allowed, every 

 load must be divided into four heaps, and so on in proportion 

 to the quantity allowed. But if the gardener should choose 

 to drop his heaps five paces or fifteen feet apart, he may 

 make such distribution of his loads as to have one hundred 

 and ninety-three heaps on the acre of land ; in which case 

 by dividing each load into four heaps, he will require only 

 forty-eight loads to cover the acre, and he may decrease the 

 quantity still more, by allowing greater distances from heap 

 to heap, or by dividing his loads into smaller proportions, so 

 as to accommodate himself to whatever quantity of manure 

 he may allot to any given quantity of ground. 



As it may not be generally known that some kinds of 

 seed are apt to lose their vegetative qualities much sooner 

 than others, the following hints are subjoined as some rule for 

 the gardener's government, provided the seed is carefully 

 preserved, and not exposed to excess of heat, air, or damp 

 ness:
