Drains should be carefully made from the 

 stables and cattle-sheds, to cisterns or wells 

 protected from the rains ; and from these, 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-

 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

 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-

 less ignorance and neglect of the tenant, of 

 these objects.
