During the last thirty-five years, Newmarket has greatly flourished, and is becoming every day of greater importance. At the time indicated above it was a poor place, many gentlemen declining to send their horses to be trained there, some of them would not believe its being possible to train a Derby winner on the heath. For several years, no winner of the Derby was trained at Newmarket. By 1860, however, fortune had begun to smile on the place, which may be said, with the advent of the Dawson family, to have commenced a career of prosperity which still goes on. Mr. Joseph Dawson came first with the horses of Lord Stamford; Mr. Mathew Dawson followed, and to that gentleman's care Lord Falmouth entrusted his horses; Mr. John Dawson likewise took up his quarters at Newmarket. Other trainers speedily blossomed into importance, and Newmarket horses began to make their mark on every racecourse in the kingdom, so that the town speedily became important as a great training centre, the best training talent of the kingdom indeed became centred at head-quarters, and from 1863 to the present year the town has flourished exceedingly. Land has of late become so valuable that it is difficult to procure a site for a house or a stable under an impossible price. The numerous persons engaged in the training stables create a large amount of remunerative business to the tradespeople, whilst the building operations of the last twenty years have given employment to a regiment of mechanics and labourers. It is affirmed that the business of horse-racing is seen at its best at Newmarket; but such a statement may be taken for what it is worth, as the arrangements made at the gate money meetings are remarkably perfect. It is quite on the cards that the racing tracks at Newmarket will speedily be so enclosed that no outsider will be able to witness the sport, various movements in that direction having already taken place.
