Some horses are liable to giddiness at work. It is not the same as choking or swooning in the collar. It seems to be a kind of apoplexy. The horse drops without the least warning, lies for a few seconds insensible, and then rises somewhat confused. After two or three attacks, the horse is sure to have more. Saddle-horses are not exempt. These horses should be kept at slow work in double harness. Their work and feeding should be always the same. Excess or deficiency of what they are accustomed to, renders the attacks more frequent. Physic may be given thrice a year or oftener. The food should never be constipating. The bearing-rein should always be free. If the horse be observed to stagger, he should be pulled up, and allowed to stand two or three minutes. When he falls, he needs nothing but time to recover his senses.

Blind Horses should not be placed within reach of a mischievous neighbor. They can not defend themselves nor get out of the way. In harness the wheel suits them better than the lead. When only one eye is lost;, the horse should work on 'he side from which he sees.

Glandered Horses often work for years after they are in« curably diseased. They require to be well fed, well lodged, and well groomed. So far as my experience has gone, medicine of all kinds is entirely thrown away upon them.

When the disease appears in a sound stud, the horse should be destroyed, or at least removed without delay. It is possible he may recover; and, if he can be kept where he can do no harm, he may have a trial. If permitted to remain, he is just as likely to give the disease to every horse in the stable, as to get better himself. It is generally supposed that glanders can not be communicated without actual application of the matter. This is not certain. I am pretty sure that, in some forms, it will spread through the air. It is prudent to suspect and to watch every horse that has breathed under the same roof with a glandered one.

When several are diseased, it may be worth while keeping them. They may be all put to one road, and kept in stables apart from the others; having men, harness, pole, and pole-chains, entirely to themselves. When it can be managed, they should not even enter the stable-yard where there are sound horses, and the men should be carefully excluded from every stable but their own.

When the horses die off, so that sufficient are not left to do the work, their place may be supplied by others, sound, but of little value. In this way, however, the disease is kept up. It is better to destroy the few that remain. Let the stalls, every portion of the stables, from floor to roof, both inclusive, be well washed with soap or sand and water. Let the woodwork be scraped or planed, and ragged portions chipped quite out. If the mangers and racks be of wood, and much wasted, remove them altogether, and replace them by others of iron. After washing, give all the stone or brick a coat of hot lime-water. Till all this is well and completely done, no sound horse should enter the stable; and even after it is done, the stable should stand empty for a week or two.
