ON THE MANAGEMENT OF THE FARM HORSE, 429 
Thrush and Cankered Frogs. 
The cart-horse is very subject to these complaints. To cure the 
former malady the following mixture answers the purpose well: 
Take of common tar four ounces, sulphuric acid six drachms, alum 
iri powder one ounce : mix these ingredients well together, and 
apply the mixture at night, first cleaning out the parts well. Keep 
the feet dry, and do not allow them to be saturated with dung and 
urine, which is but too often the case in farm stables. All ragged 
or under-run portions of the frog should be cut off, which will 
destroy any harbour there may be for the diseased secretion. It 
is necessary to use caustic when fungus sprouts up, or, in other 
words, when the case has turned to canker. The veterinary sur¬ 
geon had better manage the case then, it being out of the reach of 
any carter or wagoner. 
Estimate of Cost in rearing a Cart Colt until he be four Years old. 
Before concluding this essay, I shall endeavour to calculate this 
expense as nearly as possible. It must be subject to some variation; 
enough, however, will be shewn to demonstrate that it is not a 
very profitable concern. Taking the average value of cart colts, 
rising four years old, it will not exceed £35 each. A colt’s work 
cannot be of any considerable value before he is arrived at that 
age. Very few farmers, comparatively speaking, breed cart colts 
with the expectation of realizing much profit; full well knowing 
a much greater gain arises in converting the same quantity of food 
into beef or mutton, milk or butter. I will now endeavour to estimate 
the cost of the different items, though I still fear the attempt will 
turn out imperfect.

In specifying the items of cost, many other incidental expenses 
could be named, which would still lessen the little profit attached
