One of the prettiest pieces of true art in landscape gardening near Philadelphia is Hunting Park, designed about a quarter of a century ago by Mr. William Saunders, now of Washington. Having a wholly flat piece of ground to deal with, in that respect he was at once cut off from a great source of variety which is one of the chief elements of success in landscape gardening. He had to depend wholly on the selection of striking differences in the trees individually, and in varying the character of the groups themselves. No attention has been given to this little park of about twenty-five acres. The trees are starving in many instances, for lack of manure, - some have plead for a thinning out of quarrelsome neighbors that have almost overpowered them, - while in many places, trees that have died have not been replaced, and hence much of the original design is impaired. But, neglected as it has been, it is an excellent illustration of how much may be done to give variety to a place by trees alone, when in the hands of a master in the art.

On a flat piece of ground like this, one is almost compelled to look to trees for the material out of which to give the varied features which constitute no mean element in successful landscape gardening.

It is amazing when one looks around at what are passed as good specimens of landscape work, to note how little regard is given to this trait in good gardening. There are indeed few places known to the writer, that might not be given a wonderfully greater interest by attention to more variety in detail, and which could be easily given without adding much to the cost, and often with a decreased expense in the annual bills for maintaining such grounds. In places of any extent what is known as the wild garden has been introduced in many cases with just this result. It has added a variety that costs little to keep. Where there is a natural inequality in the surface we have a ready means of giving variety, as it affords opportunities for introducing rock gardens, fern gardens, fountains, pools, rustic bridges, statuary, and other special features, to much better advantage than where the ground is quite level. We give here a view from the grounds of "Rocky Dell Farm," the residence of J. Reynal, Esq., at White Plains, N. Y. Beautiful as these grounds are, the critical landscape artist could no doubt improve on some of the features; still occasion has been taken to bring into play many of the advantages noted which variety gives.

We call attention to the matter at this ! season, because so many elements out of which so much in variety may be afforded, press themselves on the attention with much greater force than at other seasons of the year.

In the past we have suggested that peculiar effects could be obtained by taking a few species and making an essential feature of them by successful growth for spring adornment. So also, much may be done for summer effect outside of mere leaf and bedding plants. Why are not the class of succulents used more for bedding purposes? We do not mean that they should supplant flowering things, of course. Succulents generally have no blooms adapted to cutting. Usually, in fact, they are very shy of blossoming; but they afford much varied form, and many of them have strikingly gay colors. They grow so well in our climate - asking no care - giving really so much in return for so little, that certainly we should make more use of them than we do. For vases, rock work, etc., they are almost indispensable. Amongst sedums, opuntias, and mammil-laria, are some quite hardy species - so that, winter or summer, they are self supporting contributors to our floral pleasures.

Then again, the dwarf evergreens are not made as much use of as they might be; chiefly, because we employ them too sparingly. It is usual to plant them mainly for their botanical interest. We find persons pride themselves on having this or that rare thing in their " collection," just as the numismatist values his old coins; not for the use he can make of the rare penny, but because so few possess one. The real value of these plants is their capacity for adornment, and this is seldom brought out, unless they are used in groups or masses. It may be said that they are frequently too expensive to be used on a large scale; but it is the limited demand for them which keeps up the price. If one has not the means to buy them by the dozen at once, they may be increased on one's own ground. Almost all these dwarf evergreens root very readily by layers. A slit may be made in their stems near the ground, in June, and good rich earth mounded up about them, and generally they will be rooted by the next season. Some may be increased by inarching. Common kinds may be set against the rare ones.

A little bark cut away from the stock, and from the kind to be inarched, and then the two cut places brought face to face together and tied with bark, woolen string, or any thing of that character, and they will be firmly united together before fall. Or they may be grafted on other things growing at a distance, by burying a small bottle till the mouth is level with the ground, at the base of a little plant to be grafted; fill it with water, then put a branch of the choice kind in the bottle, and tie together as in inarching, which it really is.

In planting out flowers don't take them at once from the hot-house to the open ground; set the pots out for a few days in a cold frame with plenty of air, or under a tree in a sheltered place. Before turning them out of pots, water; and when set in the earth, press the soil very hard about the flower roots. If the ground be dry, the earth cannot be pressed too hard.

Don't make the bed* very high, or the rains in summer will run off too rapidly. After smoothing the surface peg down the plants as much as possible so as to cover the surface soon. The plants also push out side shoots easier. Where small twigs can be had, split and double them like hair pins, for pegging down; where these are not at hand, small pieces of bast mat or twine, doubled and dibbled in the earth by the ends, make very fine pegs.
