the premises every year, but every week or so we pour 

 kerosene on the roosts, and in the corners of the nest 

 boxes, and sprinkle insect powder among the nest 

 material. It is seldom that we see a louse, and if we 

 have a bird that has "gone light," or is droopy, it 

 is so from some other cause than vermin. If more 

 care should be given to this louse question, as well as 

 in feeding so that the flock will not overfatten, there 

 will be less cases of reported "cholera." Is it not 

 strange that when we hear of ravages of cholera it 

 almost invariably is among the flocks of either a be- 

 ginner or a careless man ? 



And the good method for preventing disease is 

 to disinfect the houses every month or so by burning 

 sulphur in them. Take an old iron vessel and set it 

 in the center of the pen. Then take a pound of sul- 

 phur and wrap it in a newspaper. See that every 

 window is closed, and that all the fowls are out of 

 the house. After setting a light to the paper get out 

 of the building and close the door. It will not take 

 long before the interior of the pen will be black with 

 smoke. Leave it burn for. an hour or more, after 

 which open up the doors and windows and let the 

 place air well before the fowls are ready to go to 

 roost. This fumigation will not only kill any disease 

 germ that might be in the building, but it will also 

 destroy all vermin that the fumes will reach. 



Another common cause of sickness is inbreeding. 

 We realize in saying this that we are apt to raise a 

 discussion, for it is surprising how some of the very 

 best poultrymen in the country still cling to the belief 

 that inbreeding is not harmful. But their number is 

 becoming smaller every year. Inbreeding no doubt 

 retains certain markings and characteristics of a 

 strain, but it does not maintain ruggedness. We find, 

 after quite a number of years' experimenting, that 

 new blood can be gradually added to a flock and not 

 harm the strains' trade marks, but it must be judici- 

 ously done. Introducing new blood recklessly is as 

 bad as inbreeding, and therefore the poultryman is 

 compelled to study the question well, and to secure 

 his new blood only from such sources as are in line 

 with his own stock. 



In breeding turkeys, relationship must be avoided. 

 If the cock bird has considerable wild blood in him, 

 the offspring will be stronger. Where inbreeding is 

 practiced, after a few years the young will be liable 

 to have crooked breasts and other deformities.
