450 Cultivation of Grafs Land. Warping* Mowing of Hay Lands* 



that, by the aid of machinery, water may be forced up fo as to bedifperfed at fuch 

 levels as cannot at prcfent be eafily conceived. 



The fameprinciples may be applied, in many fruations, in conveying the rich 

 .liquors collected in ponds and refervoirs about the farm-yards and buildings, that 

 rare too frequently wafted by evaporation or other means, over the adjoining fields, 

 as has been practifed by Mr. Fenna, in Chelhire, and defcribed in thefecond vo 

 lume of Communications to the Board of Agriculture. 



A variety of ufeful hints and obfervations on the means of effecting the bufinefs 

 of watering on grafs lands in different fituations and circumftances.with references to 

 figures for managing the works in the different cafes, have been given by Mr. 

 Marfhall in his work on the Landed Property of England. The advantages that 

 may.be derived from the fame practice on arable lands are likewife noticed. 



The chief objection to this method of improving meadow lands is the firft ex- 

 penfe of the bufinefs ; but if it be conducted in a judic ous manner, this will feU 

 dom form any real impediment, as the almoft immediate increafe of produce will 

 amply repay the improver. And the object of thecutting of the land is of little 

 or no con-fequcnce, if it be thereby made to afford additional fupplies of food for 

 thefupport of flock, and at the fame time contribute to the gradual improvement 

 of the foil. 



As the water in thefe cafes is in a conftant ftate of motion, it is not probable 

 that any prejudicial effects fhould be produced on the health of the inhabitants, 

 though the practice fhould be conducted on the largcft fcale. 



Warping. There is a mode of improving land by warping^ or the admitting of 

 the tide waters of large rivers near thcfea upon the lands for the purpofe of depo- 

 iiting their rich materials, which are denominated warp, ar d in that way forming 

 as it were a new foil. It is much practifed in fome parts of Lincolnfhire as well 

 as Yorklhire, and has been fully defcribed by Mr. Young in his valuable Report of 

 the firfl of thefe diftricts. But as it can only be employed with advantage in a 

 very flight degree upon grafs lands as a manure, and as its application has been 

 already confidered in the management of tillage ground, it does not appear necef&quot; 

 fary to defcribe the practice more fully in this place. 



Mow ing of Hay Lands. In the cutting of grafs crops for the purpofe of being 

 converted into hay, it is neceflary that they be in the mofl fuitable dates of growth 

 and maturity for affording the befl and mofr nutritious fodder. With this view, it 

 would feem that they (hould neither be cut at too early a period, or fuffered to
