Even good plans for farm-houfes of different 

 fizes, according to the number of inhabitants, would 

 contribute in no fmall degree to general welfare. 

 The bed-chambers in farm-houfes are in general 

 too low and confined, and the whole building too 

 fmall ; this occafions too many people to be crouded 

 together, a circumftance always very unfavourable 

 to health, and the moft common fource of conta- 

 gious diforders. Good water is alfo a circumftance 

 of great moment. If this can be had from any 

 fpring that rifes to the furface of the earth, it is 

 commonly preferable to fuch as is drawn from a 

 confiderable depth; but fuch a choice is not always 

 in our power. If pond-water be ufed through ne- 

 ceflity, it mould be previoufly put into cifterns or 

 reiervoirs, covered at the top, and there fuffered to 

 fettle. Care mould be had that the water be taken 

 from a large pond, with a (tony or gravelly bottom, 

 and not fubject to become putrid. Thofe who 

 drink water of this kind fhould beware of fwallow- 

 ing the eggs or fpawn of animals, leeches particu- 

 larly, which fometimes have produced, it is faid, 

 difagreeablc fymptoms. 'omta*
