falls, and the difficulty of ensuring that absolutely boiling 

 water is employed is considerable. Still, as a means of 

 washing out mangers and flooring it is not without value. 



Eor the disinfection of clothing boiling may be used with 

 advantage, but where many blankets have to be done it is a 

 slow process, and if the latter are of wool they are ruined. 

 We shall presently consider how blankets may be disinfected 

 on a large scale. 



Method of Apjjlyiiig Disinfecting Solutions. — The best 

 method of applying disinfecting fluids to stables and stable 

 fittings is by means of a fine spray. It is vastly superior to 

 a brush, for the spray may be made to penetrate by the 

 force of the pump, while the area dealt with at one time is 

 very much greater than could possibly be reached by 

 hand. 



Apart from these considerations, the spray may be made 

 to penetrate into corners where a brush could only be intro- 

 duced with difficulty, and it is in corners, on projecting 

 surfaces, lips, and other irregularities where dust lodges, 

 and with the dust in all probability are the pathogenic 

 organisms we are in search of. 



The walls, ceiling, floors, every part of the fittings of 

 stables or cow-houses can be reached by a spray pump with 

 the utmost ease and rapidity, and no other system can 

 compare with it for effectiveness and thoroughness. 



Spray pumps may be had either to deliver the disinfectant 

 from an ordinary bucket, or attached to a barrel cart 

 which can be wheeled about, and holds 50 gallons of 

 disinfectant. Figs. 167 and 169 show two patterns of 

 these pumps, while the spraying nozzle, which is the 

 essential feature, is shown in Fig. 168. 



Limewashing may also be done by a spray pump, thereby 

 saving considerable labour and time. Fig. 170 shows an 

 apparatus for this purpose. 



Spraying may be adopted in dressing cases of contagious 

 skin disease, or for removing ticks from animals. For the 

 latter purpose a mixture of kerosene and water is employed, 

 delivered by a pump to which is attached a kerosene chamber ;
