should be kept upon clean, dry footing, and serious cases should be 

 kept in the yard or in dry stables. Four per cent, carbolized tar 

 makes a good application for cleansing and disinfecting, and keeps 

 out dirt. Treatment of the whole flock may consist in driving it 

 through a large pan containing a solution of copper sulphate about 

 four inches deep. The animals should be forced to remain in the pan 

 several minutes. This solution should be made up by dissolving a 

 pound of copper sulphate in the proportion of one to two pounds per 

 gallon of water." 41 



Maggots. 



During the hot, humid days of summer the blow-fly is trouble- 

 some to sheep. These flies lay thousands of eggs in the folds of 

 Merino sheep and in the filthy or wet fleeces of other sheep. Clean 

 and dry quarters are the best preventive of this fly. The eggs hatch 

 into larvae known as maggots, which eat their way into the flesh 

 of the animal. Animals afflicted with these parasites are easily de- 

 tected because of their restlessness. The treatment is simple and ef- 

 fective. The wool is shorn off close to the body where the maggots 

 are located and a kerosene emulsion applied. A coal tar disinfectanl 

 in a ten per cent, solution may be used. The wound should then be 

 dressed with a two per cent, carbolized salve. 



Weaning the Lambs. 



At twelve to sixteen weeks of age, lambs may safely be weaned. 

 Weaning should take place prior to June 1, for when lambs are 

 allowed to run with their mothers during July and August heavier 

 infestation with worms results. The ewes need rest after nursing 

 lambs, and should be given an opportunity to build up their physi- 

 cal condition before the mating season begins. A breeding ewe in 

 good physical condition when bred produces a higher percentage of 

 lambs than when in low physical condition. 



The lambs that are not marketed should be placed in a pasture 

 lot that has not previously been grazed by sheep that season, in 

 order that they may be kept free from parasites. No grain need be 

 fed to growing lambs destined for breeding purposes when good pas- 

 ture is available. 



At weaning the lamb should be separated from the ewe, and th< 

 latter placed on pasture that is short of grass so that the milk flow will 

 decrease. The second day after weaning the entire flock should b<
