Which expence is fiippofed to accrue annually, upon about 

 one-fourth part of the fliift of arable land, which comes re- 

 gularly in courfe for manuring ; and which the home-made 

 manure, or that produced from the farm, is not fufficient to 

 afford to that proportion of the farms a proper drefTing. This 

 calculation is ftated on a fuppofition that the wharf where 

 the foreign manure is delivered, is within diftance of making 

 three turns in a day, with a waggon and five horfes; where 

 the team makes but two turns in the day, and where in- 

 deed one load is a compleat day's work, the above expence 

 muft be proportionably augmented. 



The hufbandry mofl: generally practiced in this diftrift is 

 to make a thorough fummer fallow for oats or barley, and 

 to fow about one half of the fpring corn land with clover, 

 dunged when young, and fucceeded by wheat upon the clover 

 ley. The oat and barley etches which are not filled with 

 clover, being previoufly dunged in the winter, are fown 

 early in the fpring with beans, drilled or broadcaft, kept 

 well hoed through the fummer, and fucceeded by wheat. 

 The wheat ftubbles are haulmed immediately after harveft, 

 and a part of them are fown with tares, which are either 

 fed completely off, or only partly fed, and then left to (land 

 for a crop ; the land is then fallowed for fpring corn and 

 the fame courfe repeated. This management is found to 

 be more efficacious in eradicating the black grafs, than any 

 other at prefent known or pradifed ; and aided by the foreign 

 manure annually expended in the diftridl, produces according 

 to the prefixed table, the following average crops per acre,
