If the disease is non-existent, then all new arrivals should be 

 viewed with suspicion and kept isolated until it is certain they are 

 free from the disease ; microscopical examination of the faeces is the 

 only reliable method of ascertaining the infection. 



Newly purchased eg-gs for setting- purposes should be first washed 

 in methylated spirits, allowed to drv, and then dipped in perchloride 

 of mercury (1-2000). 



The incubator trays, drying- boxes, brooders, market baskets, 

 crates, cag-es, and any articles likely to convey infection should be 

 thoroughly cleaned and then disinfected. 



On farms, and wherever possible, a fresh site for coops and 

 hatching boxes, etc., should be selected every year, and the old 

 ground treated as recommended above. 



Method or Disinfection. 



It will be sufficient to Avash the incubator trays and drying boxes 

 with a 5 per cent, solution of Lysol, Hycol, or other carbolic prepara- 

 tion, und then allow to dry. 



Coops, hatching boxes, brooders, perches, cages, and fowl-houses 

 should be scrubbed with boiling water and caustic soda. When dry, 

 the woodwork, etc., can be limewashed, and to the wash add some 

 disinfectant, such as Hycol. 



The floor should be scraped and the scrapings burnt. Then may 

 follow either the sprinkling of freshly slaked lime or the spraying 

 with disinfectant. A very serviceable spraying fluid is paraffin 

 emulsion, which is easily prepared, thus: — 



Hard soap J lb. 



Boiling water 1 gallon. 



Paraffin 2 gallons. 



First dissolve soap in the water and then add the paraffin and 

 stir vigorously ; finally dilute with four times the amount of water. 

 The advantage of spraying is that the liquid more easily penetrates 

 the crevices and corners. A good plan is to paint the perches and 

 uprights and crevices with boiling tar, as ordinary limewash is soon 

 rubbed o£P. 



As poultry farming is becoming more important every day and 

 owners are realizing the value of wellbred stock, the first lesson that 

 should be learnt is cleanliness. Any time spent on cleaning the 

 fowl-run is well worth the labour, and at the same time disease and 

 financial loss are reduced to a minimum.
