XitzscliK Both of these pai-asites are sometimes found hi great numbers on 

 neslected cattle, and when the stalls have become thoroujthl.v infested are hard 

 U) clear out entirely: Imt this can be done by continued ett'ort and with great 

 l)enetit to the stoclv and to tlie owner. Many remedies are l^nown. We have 

 used kerosene emulsion with nnic-h satisfaction, spraying it on to the animals 

 and theu ruljbing it well in witli the hands. Any of the recognised shei'p 

 dijis will also answer and an' very convenient. Kecently zenoleum has liecn 

 used for this purpose and answers well. All of tlu' latter are used of the 

 strength advised by the makers. An important part of the treatment consists 

 of spraying thoroughly the stalls where the aninmis have stood, after cleaning 

 them out. Hoth of these lice leave the animals and hide in the cracks and 

 crevices of the woodwork.

 This is the largest louse known, measuring one-(iuartcr of an inch in length. 

 It is of a dirty white colour marked with brown. The feet are jirovided with 

 strong claws, with which they cling tightly to the hairs. Although, from the 

 nature of the animals they infest and the usual way their pens are built, these 

 lice are rather dithcnlt to eradicate, the same remedies mentioned for the 

 cattle lice will quickly and entirely kill these parasites also, as I h.ive found 

 on several occasions. It is necessary to spray the sleeping ipnirters very 

 tlioroughly. 



Sheep Louse ('rrh-liiidciii's siiliurocciJliiilHs, NiTZseii). 

 This is a very small lonse but is a very troublesome parasite, causing 

 great irritation to infested animals, wliii-li show llieir discomfort by rubbing 

 themselves and by biting at the wood, ilost of th<' severest cases of infesta- 

 tion by sheep lice have been in the winter. Sheep should be examined before 

 winter sets in. and if any lie<' are foun<l they should be (liip]ied. 



Fi.i;.\s. 

 Two speeies of fleas vei-y constantly attark man. These .-ire the house 

 flea (Piilcr initiinK) and the dog and cat ilea ( /'. xcrraticiiixt . The rat and 

 mouse flea 1 1', faxriuliix) and other fleas will also occasionally attack him. 

 Of all the fleas, that of the dog and cat is perhaps the most connnon in Imuses, 

 and being less active than the house flea is more easily eajitured. 



Hciiwilics. 

 A very concise statement of the remedies to be applieil for lieas is given 

 in Circular Xo. 1.3, by Dr. L. ( ). Howard:— 



"The larvse of the dog and cat flea will not develop successfully in 

 sitnations where they are likely to be disturbed. The use of carpets and straw 

 mattings, iu our opinion, favours their development, since the young larva- 

 can penetrate the interstices of either sort of floor covering and find an 

 abiding place in some crack where the.v are not likely to be disturbed. It is 

 comparatively eas.v to destro.v the insect in its earl.v stages (wheu it is 

 noticed), as is shown by the difllculty of rearing it, but the adult fleas are so 

 .active and so hardy that they successfully resist any but the most strenuous 

 measures. Even the persistent use of California buhach and other pyrethrum
