The time has again arrived when alterations of all kinds connected with ground-work are to be effected with the greatest advantage. If improvements are contemplated, the present is the proper time to consider and determine what these shall be. Now is the best time to study the composition of landscape scenery, the individual and collective beauty of trees, as they are clad in the beauty and variety of the "sere and yellow leaf." The garden scenery is constantly changing, however imperceptible it may be; and if this progressive change has extended over several years without interruption, it may now be proper to reflect whether or not time is producing effects that demand immediate attention. Certain trees may have overgrown their intended limits, and be producing effects the opposite to what was intended. Beads and walks which, a few years ago, seemed to have " ample room and verge enough," are now encroached upon so far as to call for immediate alteration, either by removal of the trees or altering the form or direction of the walk; the latter being the most advisable, if at all practicable.
No mechanical rules can be permitted to guide us in these and similar matters of taste; yet there are principles which must be adhered to, and which no person of refined and cultivated taste will depart front.
