Very many infantry regiments and several brigades of artillery, together with one regiment of cavalry and a battalion of the Rifle Brigade, were in huts when I visited the camp in April, 1860. It is the ridiculous system of picketing horses in the open air to which I allude as displaying a great amount of ignorance on the part of the authorities of the War Department. The system entails a great and very unnecessary loss to the country annually. When troop-horses have been used to warm stables--many of them for years--they are certain to take cold when picketed in the open air. Inflammation, influenza, greasy heels, and that dreadful disease, glanders, are almost sure to break out, and in time extend their effects to other regiments who come in contact with them or their quarters. If young horses, on being purchased from their breeders, were never permitted to enter a stable, no harm would come of the system; but moving horses from warm stables to the open air, in such an exposed situation as Aldershot, can only have a parallel in a gardener transplanting his choicest hot-house plants into the open air during the rigours of a severe winter. Aldershot, in the county of Hants, is about fifty miles from London, on the South-Western Railway. The camp is fourteen miles in circumference, and is completely surrounded by piquets (soldier-police-men), mounted and on foot; so that if any poor, discontented wight makes an attempt to desert, it is a guinea to a gooseberry in favour of his being caught, and walked back under escort to camp. When I alighted at Farnborough Station my eye at once rested upon the fine bronzed countenance of Sergeant McGuinness, of the 10th Hussars (one of the Kertch heroes), who was at that period provost-sergeant in charge of a piquet always on duty between Farnborough and the camp, a distance of three miles. No ticket is allowed to be issued at the Farnborough or other stations to soldiers until the provost-sergeants have inspected the "pass," or "furlough," which they ought to have duly signed by the captain of their troop or company.
