s A Treatise on Vegetation, ^c. 



Your dung thus drefled muft then be pur up into 

 pretty large heaps, where (hould it heat, it mufl: lie until 

 quite abated ; and tlie winter following mufl be fpread 

 out, for the advantage of the froft, and by fummer fol- 

 lowing it will be ready to put into your Compofl: heaps. 



There is another manure, which is of very great ufe 

 to the Florifts ; particularly for the many falts proper 

 for vegetation it contains, and requiring but one feafon 

 for its preparation. 



The Dutch CompoJ} for UYACitiTHS. 



This is much ufed by the Florifts in Holland, and when 

 I was lafl there, 1 obferved a gentleman's Hyacinths in 

 the highefl perfe6lion, which led me to enquire what 

 Compoft he ufed, which was no other than one third of 

 line white down fand, one third of extremely well rot- 

 ted cow dung, and one third of rotted leaves of trees. 

 This is the manure I fliall now treat of, and fliew the 

 manner of preparing it, which every Florill: fhould never 

 be without. 



Let the leaves of thofe trees and bufhes which fall in 

 the end of autumn, be gathered and laid in your Com- 

 pofl-yard ; which muft be fpread out, over which you 

 lay your cow dung, then a layer of leaves, and another 

 of cow dung, and fo alternately until your heap is Mifed 

 to 1 2 or 14 inches, but no higher : the fap and falts of 

 the dung will, in one winter, intirely rot your leaves, fo 

 that in April there will not be the leaft appearance of 

 them. 



Having thus given directions for preparing your fand, 

 cow dung, leaves of trees, and the kinds of different 

 earth to be ufed, I proceed to give their proportions. 

 To a load of what fand you can procure, after it is pre- 

 pared agreeable to the foregoing diredion, take two 

 loads of cow dung, in which the leaves of trees have 

 been rotted, and the whole fifted and made fine, toge- 

 ther with one load of fine riddled and prepared earth 

 either of the moffy^kind, or of the black earth, I before 

 defcribed, but by no means fuch as have any particles 

 of clay. This mixture fhould be prepared in May, by
