chamber where they accumulate. When all the stock have passed 

 through, the flies in the glazed box can be destroyed by the spray 

 of tobacco or quassia water, or the fumes of burning sulphur, tar, 

 pumpkin leaves, etc. 



To Destroy Flies in the Buildings. This may be accom- 

 plished in the absence of stock, by thorough fumigation with smoke 

 from pumpkin leaves, green grass or vegetables, tar, turpentine, 

 or sulphur ; by filling the closed building with chlorine gas ; by 

 dusting the whole building with insect powder ; or by spraying 

 the interior with quassia or tobacco water. 



The flies' love of light may be availed of by making one small 

 opening into a tight glazed box and then clo.sing doors and win- 

 dows to make the stable quite dark. The flies will gather in the 

 glass box and may be destroyed as suggested above. 



Even when the animals are stabled, bundles of ferns, grass, 

 evergreens, etc. may be suspended at intervals from walls or ceil- 

 ing, and at night, when covered with flies, they are burned or 

 shaken over a fire. 



Fiesh chloride of lime set around in saucers will do much to 

 drive out the flies. Sweetened quassia-water in dishes will kill 

 the flies without endangering larger animals. Sticky fly paper and 

 fly traps may be employed. Railliet advises to have two boards 

 hinged together .so that they will hang apart like the two limbs of 

 an inverted Ai to smear the inner sides with syrup, hang it on the 

 stable wall and whenever one pa.sses to close it suddenly and 

 crush the flies. 



To protect the bodies of Animals in Stable and at Work. 

 The bodies may be covered by thin linen sheets. The common 

 covers of netting or of leather thongs are still better as leaving 

 the .skin free to the air and for evaporation. A long fringe of 

 twine or leather does much to encrease the protection. Netted 

 ear caps are of most essential value. A simpler resort is the use 

 of leafy branches attached to the harness, and moving with the 

 motions of the animal. 



Skin applications which are obnoxious to flies are also used. A 

 decoction of walnut leaves, or of tobacco (3 ozs. to i qt.) rubbed 

 on the skin once a week ; the fresh leaves of these plants rubbed 

 on the .skin ; the leaves of ailanthus ; infusion of quassia, aloes, or 

 asafoetida ; creolin (5:100) ; oil of cade ; oil of laurel ; oil of tar in
