As to fat cattle for market, after they are trained, they should not go a yard except by rail or steamboat. As to trucking store cattle, this must be regulated entirely by the season of the year and the weight of the cattle, &c. I have always had a reluctance to truck store cattle if I could possibly avoid it, not only for the expense, but for the risk incurred from dirty and infected trucks. I would recommend, if the cattle have a distance to travel in March, April, and May, and until they have been fourteen days at grass, that they should be trucked. But I have often been astonished at the recklessness of farmers buying cattle in a fair, going straight to the nearest station, and turning them into any dirty truck they can get--(when are trucks other than dirty?) The danger is great; despite the utmost circumspection, even the most careful may sometimes be caught. If those who act so escape, it is not owing to their good management. I would recommend my friends, when they go to a fair for the purpose of purchasing cattle, to take a confidential servant of their own along with them, or else make it a part of the bargain that the owner keeps the cattle for a certain time, till the buyer can get the trucks properly cleaned--which I find no difficulty in getting done--so that before they allow their cattle to be trucked they may be satisfied the trucks are thoroughly cleaned. They should be washed over with chloride of lime, or, what is still better, given a fresh coat of paint. Three to four shillings will paint a truck; that is a small matter--say sixpence a-head; but care must be taken that the paint is dry before the cattle are put into the truck, else the beasts will be poisoned. If this is neglected, there is great risk of bringing home foot-and-mouth disease, or even the lung disease. Some say that it was impossible to attend to such an operation--that business called them home, and that people would not take home their cattle. I have never found any difficulty in my own experience; but I must allow that some sellers are too distant to send the cattle home. In such an emergency the beasts should be laid past upon a little hay or straw for a day in the neighbourhood; there is always a field to be had, or the market green. What is a day, or a man or two, and a night's hay, if your beasts come safe? Disease has been carried in this way to hundreds of steadings, and the results have been most disastrous. The day's rest will be a great advantage to the cattle after the fatigue of standing in the market. The main object with store cattle should be to keep them sound on their feet and free from disease. If their transit is to be by rail, the quality of their food for a day or two is of minor importance; they will soon recover.
