Management of hairy Cou’s. 
its intense itching, carry with them the tags of the wool, the loss 
of which is an early symptom of the disease. At a later period 
the crusts are replaced by another set of thicker, firmer, adherent 
scabs, which are still further enlarged by the outward migration 
of the parasites. As they abandon the centre of the scabs these 
are again replaced by a peeling off of the external layers of the skin, 
which gradually heals, whUe the disease slowly progresses at the 
outside. The complete cure is very slow, and the skin remains thick 
and folded for a long time. In sheared sheep the skin becomes 
covered by a thick, dry crust like parchment, while beneath it remains 
much swollen. 
Late Symptoms and Diagnosis . — The fleece of scabby sheep 
presents a characteristic rough look. In places the wool is stuck 
together in masses ; in others it fails, while in others, which are ap- 
parently sound, it can be easily plucked off. The rubbing and scratch- 
ing indulged in by the sheep not only tend to tear away the wool 
but increase the irritation of the skin, which may become intensely 
inflamed and swollen, and finally end in a superficial death of the 
part. Unlike Sarcoptes, the Fsoroptes seek the longest, thickest 
wool. They begin their attack along the back and extend to the 
neck, flanks, and rump. The pests are rarely found in the region of 
the chest and abdomen. They are collected in masses on circum- 
scribed surfaces. The scabs they produce constantly increase at 
their edges, and their number depends on the number of places 
invaded. Owing to the closeness with which sheep congregate and to 
their \dolent scratching, the parasites become very generally scattered, 
and finally the scabs may run together. 
While few of the parasites are present in the older diseased 
parts, at the edges of the scabs they can be found in swarms. They 
look like little white points with a brownish extremity. If picked 
up by the point of a knife or a sharp stick and placed on the hand 
they will be seen to move. The six-legged young, the eight-legged 
adults, the sexes, couples joined together, and the eggs of this 
injurious parasite, can easily be identified by the aid of a low- 
power magnifying glass.

MANAGEMENT OF DAIRY COWS. 
The housing, feeding, and general management of daiiy cows con- 
stitute a subject of primary interest to all agriculturists who are 
practically engaged in dairy farming. In the following brief notes 
I have recorded various points of practice which I have put to the 
test during my fifty years’ experience in farming. 
I will take the case of a dairy of ten cows, and describe the 
mode of feeding, housing, and management for one year, commen- 
cing at Midsummer. This is the date at which they require especial 
attention, for it will be found that if a cow, which has calved
