 the roofs of the dwelling-house and offices, into tanks 

 properly constructed, and having no communication 

 with the soil. Should not the buildings be conveniently 

 placed for affording to the cattle a supply of water from 

 the tank, or should the extent of such roofs be insuffi- 

 cient to collect the quantity of rain water that may be 

 required, sheds or hovels, covered with tile, should be 

 erected in a central field, conveniently situated for secur- 

 ing to the cattle their daily supply. A farther benefit will 

 ensue by the shelter and protection that such sheds or 

 hovels will afford the cattle. This method of collecting 

 rain water (and which is practised in many countries) 

 may with great advantage be adopted in the upland,
