Such is the diurnal ceremony of training; varying the length and speed of the morning gallops by the flesh, wind, substance and condition of the horse; with such intervening SWEATS (which see) as circumstances may justify, or render necessary; in all which, training grooms of the best judgment, and most industrious observation, are liable to err. Horses are seen to _train on_, others to _train off_; or, in plainer terms, some horses have great speed at _three_ and _four_ years old, who never make a display of any after; and many have made no promise in the _first_ or _second_ year of their running, who afterwards became most capital racers. As a recent instance of this, reference may be made to "SIR SOLOMON," which see. No small degree of penetration is necessary to ascertain when a horse is trained the _nearest_ to the utmost point of his SPEED; most horses are _over trained_, and are, of course, the likeliest to be beaten, or lamed, whenever they are brought into competition with a powerful opponent; who, by having been _less_ trained, is _more_ above his work; or, in other words, better adapted to difficulty, and a severe struggle for victory, should it happen to ensue. TRAMMELS—are a collection of side and cross-lines, having leather loops at the ends, with which horses are trammelled for the operations of _nicking_, _docking_, _cropping_, &c. TRAMEL-NET—is a long and large net for taking birds by night with lights; a practice occasionally enjoyed by the lower class of rustics on a winter evening. TRAVELLER—has been a name of so much celebrity upon the TURF, that it cannot with propriety be omitted. _Old Traveller_ was a winner of a great many plates, and afterwards proved himself a stallion of much estimation: he was the sire of _Squirrel_, _Dainty Davy_, the dam of _Morwick Ball_, &c. &c. He was bred by MR. OSBALDESTON, foaled in 1735, got by _Partner_, dam by _Almanzor_, who was got by DARLEY'S _Arabian_. _Young Traveller_ was bred by Mr. Coatsworth, foaled in 1746, got by _Old Traveller_, dam by _Bartlet's Childers_. The last _Traveller_ was bred by MR. HUTCHINSON, foaled in 1785, and got by _Highflyer_, dam by _Henricus_, who was got by _Black and all Black_. In 1789, when four years old, he beat a son of _Orpheus_ over New Malton, one mile and a half, for 100 guineas. Two days after, he won a sweepstakes of 10 guineas each over Malton, beating four others. The next day he won a 50_l._ Plate, beating three others. At York he won the Stand Plate of 50_l._ beating _Cavendish_, _Spangle_, and a son of _Orpheus_. In the August York Meeting he won the City Plate of 50_l._ added to a subscription purse, beating _Gustavus_, and _six_ others. He was then purchased by His Royal Highness the Prince of Wales; and in the Houghton Meeting at Newmarket, beat the Duke of Bedford's _Grey Diomed_ over the Beacon Course for 500 guineas.
