The plan of the Arboretum was made in May, 1839; and, being approved of by Mr. Strutt, as soon as the crop of hay was removed from the ground, in the July following, the work was commenced by Mr. Tomlinson, a contractor for ground work, who laid out the walks, made the drains, and raised the general masses of the mounds. The mounds were afterwards moulded into suitable shapes, and connected by concave sides and lateral ridges with the surrounding surface, under the direction of my assistant, Mr. Rauch, who also superintended the planting of all the trees and shrubs, and all the other details connected with the ground, till the completion of the whole in September, 1840. The trees and shrubs were supplied chiefly by Messrs. Whitley and Osborn, but partly also by Mr. Masters of Canterbury; and the miscellaneous collection of roses was furnished by Mr. Rivers of Sawbridgeworth; the mistletoe was supplied by Mr. Godsall of Hereford; and some species, which could not be procured in the nurseries, were obtained from the Horticultural Society's Garden. The lodges and pavilions were designed by Mr. Lamb, as already mentioned: the north, or main, lodge in the Elizabethan style; the east lodge in the Tudor style, and in that variety of this style which was prevalent in the time of Henry VII.; and the pavilions in the style of James I. They were all built by Mr. Thompson of Derby; and the gates to the north, or principal, lodge were cast from Mr. Lamb's designs by Messrs. Marshall, Barber, and Co., of Derby. MANAGEMENT OF THE DERBY ARBORETUM. Supposing that the curator will occupy the north lodge, and that two labourers will occupy the other two cottages, I feel confident that these three persons will find no difficulty in keeping the entire garden in the very highest order at every period of the year. What I consider to be the highest order consists in the following particulars: - The walks should be at all times perfectly dry, smooth, firm, free from weeds, worm-casts, or other extraneous matters, and with the gravel of a good colour: the turf equal in thickness, free from all broad-leaved plants except clover, closely mown, smooth, firm, dry, and everywhere without worm-casts, mole-hills, ant-hills, dead leaves of trees, bits of paper, or any other extraneous matter which may be blown about, or left on it by visitors: the flower-garden perfectly free from weeds, and every bed filled with plants in a healthy state, and the beds well covered with flowers: the vases filled with flowers, in the manner above described, from the middle of May till October; the flowers being in pots, and either of green-house or hardy kinds, named on a card tied to the narrow part of the vase, and changed not seldomer than once a week; the same species not being more than twice introduced during the same season. All the trees and shrubs to be kept without dead wood, perfectly free from caterpillars, aphides, curled leaves, honeydew, leaves which have been killed, or branches which have been broken accidentally, and from flowers or fruits which have decayed and not dropped. The climbers or twiners to be kept tied up; the spaces round the trees free from weeds; the seats quite clean; the name tallies in complete repair; the boundary fence, lodges, and gates, in complete repair; and the labourers, and their wives and families who attend on persons who enter the garden or the lodges, clean and neatly dressed. This may be considered as the criterion of good regular management; but there are certain points to which I wish to direct the special attention of the curator and of the public, and especially of the public press.
