How applied. 



dirt has been carefully buried, the entire surface which 

 has been contaminated, or is likely to have been con- 

 taminated, should be covered with a layer of chloride 

 of lime in powder. The powder should be worked 

 about with a broom until equally distributed. It is 

 intended to disinfect the water to be used in the 

 washing process which is now to commence. Clean 

 water, from a hose in which it flows under pressure, or 

 from a force-pump, garden-engine, or from large 

 watering-pots or water-cans, or poured freely from 

 buckets, should now be applied to the entire surface 

 by one person, while another at the same time scrubs 

 the entire surface; and particularly all crevices, joints, 

 and irregularities. The washing water and chloride of 

 lime are then to be worked down the gutters, into the 

 sinks, cesses, or natural watercourses. No washing 

 water from any infected place or thing should ever be 

 allowed to flow into any cesspool, urine-hold, dung- 

 heap, pond, sewer, or natural watercourse, without 

 having previously been mixed and stirred with a 

 liberal amount of chloride of lime. When the place 

 has thus been scrubbed until the water flows off clean, 

 it is ready for effectual disinfection. 



2. For this purpose a solution of chloride of lime in 

 water, in the proportion of one pound of the powder to 

 one gallon of water, is made. For the lair of one 

 animal from six to ten gallons of such fluid should be 

 prepared. This fluid is now distributed over the 

 whole surface to be disinfected, gradually, by squirting 

 from a syringe, or by pumping through a force-pump, 

 garden-engine, or by watering from a watering-pot or 

 can with a finely pierced rose. All woodwork, stones, 

 bricks, cement, mortar, all fixtures of whatever mate-
