but such injury has not been of a serious char- 

 acter. The chief objection to the lime and sulphur 

 dip is that it requires some time and attention to 

 make it, but this is not a serious matter where there 

 are thousands of sheep to be dipped. The pro- 

 portions commonly recommended are twenty-four 

 pounds of sulphur, eight pounds of lime in one 

 hundred gallons of water, the whole mixture to 

 be thoroughly boiled and maintained at a temper- 

 ature of one hundred and ten F. while the sheep 

 are immersed. None of the dips commonly rec- 

 ommended for sheep can be safely used in a 

 strength sufficient to kill the eggs of the mite. 

 They only kill the mites of different ages. It is 

 therefore, necessary in the case of scabby sheep 

 that they be dipped a second time after an inter- 

 val of about ten days. The reason for this is 

 that during this interval all the eggs which were 

 not destroyed by the first dipping will have hatched 

 and the young mites will thus be destroyed. 



Stomach Worms. Mention has already been made 

 of the stomach worms in the southern states. 

 This small worm which lives in the stomach 

 of sheep, goats and calves and is not over 

 three-quarters of an inch long and about like a 

 hair in diameter, causes a most serious disease of 

 sheep throughout the country from the Mississippi 

 valley eastward and north and south. It begins 

 to make its effect visible in May and in nearly all 

 cases where lambs are unthrifty and show a dry 

 papery skin during the summer they are infested 

 with stomach worms. The examination of the 

 stomach of one of these animals will show the pres- 

 ence of the worms. A number of good remedies 

 have been devised for stomach worms, but there 

 is the serious objection against all of them that
