their interstices and thus to contaminate good water, the water, if any 

 serious doubt exists about its purity, should be boiled, and stored in 

 some clean place where dust cannot fall into it; the tank or jar must 

 be covered. 



Speaking generally the deeper the well the better, and if any hard 

 stratum exist in hills in the vicinity, artesian water may perhaps be 

 struck at a reasonable depth. 



Pure streams from the hills are probably the soundest water in 

 this country, aqueducts of bamboo are cheap, and can be made over 

 long distances satisfactorily. Always inspect the catchment area. 



All the rivers of this country are polluted to some degree, and if 

 river water is the only possible source of supply it must be filtered 

 and boiled. That portion of the river near the lines should be divided 

 into three parts : (i) An upper reach for the drinking and cooking

 for watering cattle ; (3) A lower reach for 



If rain water is the only source of supply it should be stored in 

 large underground tanks as at Gibraltar and other unfortunately 

 situated stations. 



All tanks and wells should be protected from the entrance of 

 surface flood water, unless the surface over which the water flows is 

 above reproach, if, on the addition of 4 ozs. of permanganate of potash 

 to an ordinary-sized well, the water does not become and remain pink 

 for about an hour, the water must be looked upon as doubtful, and 

 measures should be taken to further purify it or to have it analysed. 

 The permanganate should be mixed in a bucket before being poured 

 into the well. 



2. Ventilation. The question of ventilation involves little extra 

 expense, as obviously the less we place between ourselves and " God's 

 £ood fresh air" the less it will cost us in houses, and yet the better 

 we shall be, the present Kuchi is wrong in principle— by the present 

 ^uchi I mean the one which has a straight attaped back, a short roof 

 behind and a longer roof in front, under which is a verandah where 

 cooking, etc., is performed— its chief mistakes are :— 

 (<*.) The roof is not high enough as a rule. 

 (6.) There is not sufficient ventilation above nor below, in 

 front nor behind the cubicles or sleeping rooms. 



(c.) The verandahs, being also kitchens, frequently are the 

 receptacle for all sorts of rubbish. 

 , After mature consideration and ample proof of its benefits I now 

 beheve that there is but one ideal tvpe of li, 



; which is advisable
