cresol solution is rcconinuiKkd. 'I'hc vh'wi tiling is to use an 

 effective (lisinfcctant and plenty of it, and apply it at least twice. 

 A discussion of disinfectants ininic(liately follows this section. 

 To conii)lete the cleaning of the house, after the second spraying 

 of disinfectant is dr\- apply a liquid lice killer (made by putting 

 1 part crude carbolic acid or cresol with 3 parts kerosene) lib- 

 erally to nests and roosts and uiai-by walls. After all this is 

 done tlu' hou-c will be clciiii. In houses cleaned annually in this 

 wa\- the lir>t step is taken towards hygienic poultr\' keeping. 



The same ])rinciples which have been here brought out should 

 be applied in cleaning brooders, brooder houses, and other things 

 on the plant with which the birds come in coiitact. 



What has been saitl has reference primarily to the annual or 

 semi-annual cleaning. Tt should not be imderstood by this that 

 no cleaning is to be done at any other time. On the contrary 

 the rule should be to kec]) the poultry house clean at all times, 

 never allowing filth of an\- kind to accumulate and using plenty 

 of (Hsinfectant. 



Disiiifcclioii. — Tn the matter of disinfection there are several 

 options open to the poultr\nian. Me ma_\- make his own disin- 

 fectant, or he may i)urchase proprietary compounds like Zeno- 

 leum, Carl)olineum or a host of other "eums" which confront him 

 at every turn in his reading of poultry periodicals, or he nvdx buv 

 a plain disinfectant like formaldehyde, or carbolic acid. 



The ENperiment v^tation has tried various disinfectants with 

 a view to linding the mt)st useful, when the factors of eflicienc}-, 

 ease of a]:)plication and low cost, are considered. There is prob- 

 al)l_\- no more effective disinfectant than formaldeh}-de, Init after 

 trying it out it was nece.ssary to abandon it as a general 

 poultry house disinfectant. The difllculty was that a man couM 

 not stand the fumes long enough to spray and scrul) out thor- 

 oughly a pen. Formaldehyde is very good where it can be used, 

 and there is no cheaper disinfectant, efficiency considered. Dr. 

 P. T. Woods has recently advocated the formaldehyde gas meth- 

 od for disinfecting poultry hou.ses, u>ing the permanganate meth- 

 od of generating. This, however, is indicated only for rooms 

 which can easily be closed up air tight. It costs too much in 

 time and trouble to make an\- form of "fresh air" poultrv house 

 even moderately air tii;ht. The formaldelude gas method is 

 wdl adapted to disinfecting and fumigating feed rooms, incuba-
