d4 On the Use of Green Vitriol of Iron, 



Answer to Queries. 



1. The ashes have been long known as a manure, and 

 the demand is on the increase. 



2. The quantity usually laid on an acre, by spreading or 

 sowing it, is fifty bushels, either on grass or arable land. 



3. It is laid on hot land. By hot land we understand 

 sandy, gravelly, chalky soils of a dry nature, such as arc 

 burnt up on the long continuance ot hot weather. It is 

 most commonly used for grasses ; but is in considerable 

 esteem as a manure for oats or barley, on land of the na- 

 ture abovementioned. 



4. The vegetable effect is surprising, inasmuch as it will 

 double or treble a crop of any new sown grass, such as tre- 

 foil, &c. I have seen the benefits arising from it on old 

 pasture land much overgrown with moss, which it effec- 

 tually destroy^, and produces in its stead white or Dutch 

 clover. You may trace to an inch the cessation and re- 

 commencement of this manure. It is observable, that near 

 the fire-heapSj as far as the wind can carry the lighter parts 

 of the ashes, the production of clover is sure to be abun- 

 dant : it is equally favourable to the grov. th of barley or 

 oats. 



5. It is not mixed with lime, or any other manure. 



0. These ashes are bought by a set of higgle rs, who carry 

 them in bags loaded on asses to a considerable distance, 

 where thev are known to be in great repute; they nuist 

 come excessively dear to the consumer by this mode of con- 

 veyance. The farmers in the vicinity send for them in 

 waiwons, particularly Mr. Erumigcr, near Sundon, in I'ed- 

 fordshire, a considerable and intelligent farmer, who in- 

 creases his consumption every year, both for his grass and 

 arable land. 



3. The Sail of Peat, or Du^t. 



Answer to Queries. — !. The dust or grav saline substance 

 is produced by beating the earth containing this salt to a 

 powder; it is found in particular spots, not universally, flic 

 earth not being equally impregnated with it in all places : 

 it has not been knov;n as a manure above six years : hut f)ii 

 trial oreatlv increases in reputation and demand. 



2. Fifty bushels are the proper quantity per acre. This 

 should not be exceeded, for if it be laid on in too great 

 abui;idance it may prove extremely deleterious. 



:5. It is used for cold lands. "By cold lands we under- 

 stand clayev, or any wet grounds. 



4.. It will much improve the vegetation of sowed grasses
