should be avoided. The average sheep herder seems to have a desire 

 to use old bed grounds, and unless means are taken by the owner tp 

 prevent it he Avill continue to bed the flock on old infectious bed 

 grounds after they have been dipped, thus constantlj^ exposing the 

 sheep to reinfection. Corrals, pens, chutes, and sheds can be disin- 

 fected, and they should either be cleaned and disinfected or de- 

 stroyed if they have contained infected sheep. Eemove all manure 

 and litter down to a smooth, hard surface and burn the manure and 

 litter so removed or spread on a field and plow under. Spray the 

 entire surface of fences, grounds, and floors, as well as the walls of 

 sheds or buildings, with a disinfectant, such as a coal-tar-creosote 

 or cresylic-acid solution mixed to double the strength recommended 

 for dipping. The w^ork should be well done, otherwise it will not 

 prove successful. All brush corrals on a range where scabby sheep 

 have been should be burned. Corrals of a more permanent nature 

 may be moved to new locations, but the lumber should be disinfected 

 by spraying or passing through the blaze of an open fire before 

 being used. 



DIPPING PLANTS. 



There are numerous kinds of dipping plants in use, the size and 

 style varying according to the conditions Avhich are to be met and 

 the individual taste of the owner. The farmer who has but a small 

 flock to dip can use a small portable vat as shown in figure 18, turn- 

 ing a part of his barn- 

 \ yard or sheds into 

 catch pens for tempo- 

 rary use, but if he is 

 in the sheep business 

 to stay he will find it 

 advisable to make ar-

permanent nature. Portable galvanized-iron dipping vats, called 

 " hog vats," can be purchased ready-made and will answer the pur- 

 pose very well for dipping small lots- of farm sheep. A dipping bag 

 is sometimes used for dipping when there are only a few shee}) to be 

 dipped at different points in a given section. For this purpose it has the 

 advantage of being easily transported. It is made of heavy canvas, 

 known in the trade as No. 40, and is constructed as follows: Two 

 strips of canvas 8 feet long and 2() inches wide are sewed together to 

 form a bag 48 inches deep and 04 inches in circumference. Seams are 

 triple-sewed, top and corners reinforced with leather strijis riveted on. 

 (See fig. 19.) Iron rings held by leather ears are riveted to the upper 

 part of the bag as shown in the cut. The bag is filled Avith dip, the
