ROT. 333 



it has been a precept with careful shepherds not to let tlio 

 sheep graze on dewy grass, or wet and marshy land? 

 Why the clew and wet land was considered so dangerous 

 none could tell, and least of all the bucolic guardian. 

 Although unable to give a reason why, he could aver and 

 prove that it was so. The rational conclusion is, that 

 many creatures pass the early portion of their predatory 

 existence in the bodies of one species of animal, and their 

 maturity in another. Their eggs are deposited in the 

 former, but are not developed until expelled and cast upon 

 the earth or manure-heap to shift for themselves. 



They lie on the smoking dung-pile or such places, and 

 far away from the sheep, in which they can hnd food and 

 develop themselves. The rain washes them into the earth, 

 or they are carried to the fields with the manure. The 

 humidity serves to develop them ; they fix themselves 

 upon the moist grass, and with it these tiny enotozoa are 

 carried into the stomachs of the sheep. Once there, their 

 work is soon accomplished. 



Treatment. The successful treatment of this disease 

 embraces particularly that of prevention. As before men- 

 tioned, it is chiefly caused by Avet and damp pasture 

 lands — hence the proposition for their restoration will be, 

 First, their removal to a high and healthy pasture, giving 

 them hay and nourishing food, such as a little bruised oil 

 cake, or linseed-meal, and placing covered troughs in the 

 field containing rock, or common salt, which sheep are 

 very fond of licking, and which moreover regulates their 

 bowels, and gives them an appetite for food and water. 

 Second, give each sheep ei)Soni salts, two ounces; oil of 

 turpentine, one ounce ; pulverized ginger, half an ounce. 

 To be given in half a pint of molasses-water, to be followed 

 up with tonics, if they are found necessary. The following
