feedstuff. Birds should lie fed out of troughs frequently dis- 

 infected with a five per cent solution of car])olic acid, and 

 the water they drink should be similarly guarded. Sick birds 

 should be immediately removed from the flock and the dead 

 ones cremated. The henhouse and nests should be cleaned 

 thoroughly each day and sprayed with whitewash to which 

 sut^cient crude carbolic acid has been added to make it five 

 per cent of the whole, or creso, zenoleum or creolin should be 

 used, of the same strength. 



A type of spray pump convenient for applying this spray 

 is shown in Fig. 26. The henhouse mav also be disinfected

with f ormaldehyd. as follows : Close tightly all doors, win- 

 dows, cracks and other openings, and for each 1,000 square 

 feet of space in the building, use twenty ounces formalin 

 (torty per cent f ormaldehyd) and sixteen ounces perman- 

 ganate of potash. Place these two materials in a vessel and 

 place in the middle of the room and leave for several hours. 

 The yard should be cleaned every day. If the yard be small 

 it may be disinfected by covering it with straw and burning 

 the straw. 



For the birds intestinal antiseptics are indicated; the sul- 

 phocarbolates compound in one-half grain doses twice daily 

 has given us the best results. Other intestinal antiseptics are 

 hydrochloric acid, one teaspoonful to each quart of water, one 

 per cent of copperas and potassium permanganate. 



The following is an account of three of the tests which the author 

 made of the 30-grain sulphocarbolates compound tablets. 



"One flock consisted of sixty birds. Several were sick at the time 

 treatment was commenced, and four had died. The discharge from 

 the bowels was of a greenish-yellow color, somewhat simulating 

 fowl cholera. One tablet was dissolved in a pint of water, and this 

 fluid mixed with bran and corn chop. The mixture was then fed 

 in clean troughs. In this way each bird got approximately one- 

 half grain. This was repeated night and morning. No additional 

 birds became sick; only two of the sick died: and the rest recovered. 



"Another flock consisted of ITo baby chicks. As soon as these 

 birds were taken from the incubator they were fed tne unhacched 

 eggs that had been cooked and chopped. This mixture was reported 

 to possess an offensive odor. The birds began dying, with symptoms 

 of diarrhea, white pasty vent; weakness, dullness, drooping wings, 

 etc.; one-half the flock died before treatment was commenced. 

 One-half tablet was dissolved in warm water and the bread satu- 

 rated with it. The birds immediately quit dying. 



"Still another flock consisted of 200 birds, including a few tur- 

 keys. Cholera had appeared on the premises the fall before. The 

 outbreak was studied in the field and in the laboratory. The 

 cholera germ (Bacillus aviscpticus) was isolated. In the last out- 

 break fourteen birds had died and several were sick. Treatment 

 similar to that described above was used. Water containing the 

 sulphocarbolates was kept constantly before them. No more birds 

 were taken sick and no more died after the sixth day."
