I have had fewer roarers than most men for the number of horses in my possession, in fact, only two, one of these went so, when lent and out of my stable. The loss in valuable horses from roaring is enormous. I think a friend of mine lost £700 in one season from roarers, I have the confidence to think that had he pursued the Water-system all his horses would have been saved. Be assured, water is as applicable to the animal as the human subject--fever is the bane of the one as much as the other, and water is the antidote. Why are cart-horses so much healthier than higher fed horses? simply because the former live much more after nature than the other. A cart-horse goes to a pond and drinks what he likes, not so with the blood horse, he must only have a certain quantity, and this at stated periods; this I conceive to be wrong, and have in consequence for the last six years always kept buckets of water in the horses' boxes, so that they might drink when they liked. My friends have often said, 'But you do not allow them thus to drink when going to hunt?' 'Certainly' was my reply: if the animal always has access to water, he never distends his stomach, and by constantly sipping, fever is kept down. We do all we can to encourage fever, and then have recourse to strong drastics and bleeding! Constant water cools the animal, and the gentle sweats, which the blankets produce, operate as safety valves."--_January 5, 1848._ When in Ireland, visiting the far-famed dairy farm of Mr. Jefferies, in the neighbourhood of Cork, I was informed by the bailiff, that out of every seven cows attacked with an epidemic which raged at that time, on an average five had died, and that the loss on that estate had not been less than 2000_l_. On my suggesting hydropathic treatment, the bailiff said that some time ago a traveller by that means had cured him of rheumatism; this determined him on trying it upon the cows: success crowned his efforts; instead of losing five out of seven, he saved seven out of nine; this treatment, however, at once so novel and so troublesome, he found extremely difficult to prosecute, servants could not be induced to use the necessary friction, or endure the toil which a number of sick animals entail: this, together with the discouragement and ridicule thrown upon his proceedings by the veterinary surgeon, caused him to desist. The following is a letter which I subsequently read from the bailiff-- "Dear Sir--I am most anxious to communicate with you as to the efficacy of the cold-water cure, when applied to cattle affected with the late epidemic. "About six months ago, I had it tried on nine head of horned cattle; seven out of the nine recovered, and are now doing well. I feel quite confident that, if the cure be generally [Transcriber's note: originally 'genenerally'] known, and properly applied, much may be done in the recovering of diseased cattle. "I am, Dear Sir, your obedient servant, THOMAS B. MARTIN.
