The magnitude of Mr. Myers’ establishment may be, in some degree, estimated when we state that its performances employ no less than 200 persons--as equestrians, acrobats, clowns, musicians, children, &c., and 200 performing animals, comprising 132 horses, 18 ponies, 9 elephants, 7 lions, 6 camels, besides monkeys, dogs, and mules. The estimated value of _matériel_ alone is £150,000, and the daily expenses are over £250. Another idea of its extent may be gained from a few facts as to its transport to England, which required a train of no less than 46 waggons, besides passenger carriages, for the conveyance from Paris to Boulogne, where it was transferred to the two steam-vessels _Leo_ and _Rhine_, which were specially detached from the General Steam Navigation Company’s Continental service, for the voyage to London. The area of the stabling and harness-rooms at the Crystal Palace is no less than 27,456 square feet; and the dressing-rooms alone occupy 3,472 square feet. The elephants, horses, and camels require about 10,000 pounds of corn, 8,000 pounds of hay, 8,000 pounds of straw, 2,000 pounds of bran, and 3,000 pounds of potatoes per week; while the lions consume 400 pounds of beef per week. Career of Mr. Myers. Mr. J. W. Myers, the proprietor of the largest Hippodrome in the world, was born in New York in 1828. Though still in the prime of life, he is a veteran in his profession, having commenced his public career at the early age of nine by apprenticing himself as an equestrian to Aaron Turner and Sons, partners of the celebrated Barnum. _Ex nihilo nihil fit_, and Mr. Myers thus early recognised the truth of the proverb by taking care to be provided with the small though substantial capital of one halfpenny, with which, as the nucleus of fortune, he fled from his home. He made rapid progress in his calling, and soon distinguished himself as being the first who ever did a double somersault over horses. A few years’ experience placed him foremost among equestrians, and at the age of twenty-one he started a Circus and Menagerie of his own, with which he travelled over the United States for seven years. He then sold his property to Mr. John Wilson (whose establishment was at the time the largest of its kind in America) and came to England, having, shortly after his arrival, the distinguished honour of performing before Her Majesty the Queen and the late Prince Consort, at Windsor Castle. Mr. Myers was for seventeen months engaged with Messrs. Howes and Cushing, and at the expiration of that time he again formed a company of his own, and performed with great success at Birmingham and other English towns. Leaving England for the Continent he commenced the career which has culminated in the formation of an establishment of unprecedented magnitude.
