Drains should be carefully made from the 

 stables and cattle-sheds, to cisterns or wells 

 protected from the rains ; and from these, the 

 urine should be taken and thrown over the 

 dung-heap, which should be open to the air ; 

 there is little danger of too much water added 

 by the rains, if not under the dripping of a shed. 



I am convinced that stable and yard dung, 

 saturated with urine, and preserved in this man-

 pared in the usual manner, that is, by being 

 thrown into the open yard, and where the urine 

 of the stables and sheds is not only suffered to 

 run away, but the yard laid in such a manner 

 that the dung is washed by the rains, and the 

 drainings wasted. 



It is a little singular that landlords, well aware 

 that on the supply of manure depends the value 

 of the farm ; are in many instances so jealous 

 of having all the produce of the farm spent on 

 its land, that they will not permit their te- 

 nants to sell a load of straw ; and yet they not

 constructed receptacles for preserving the ma- 

 nure, themselves ; but will not regard the care- 

 less ignorance and neglect of the tenant, of 

 these objects.
