It is often objected to us as a people, that we are too forward to make haste. We have little credit for extreme patience. Whatever we have to do, must be done at once. "The more haste the less speed," is too old fogyish for a modern proverb. It might do in the days of stage coaches, and spinning wheels, but tastes mouldy in our fastidious mouths.

Nor are we much to be blamed. Life is short, and few of us come into the world with silver spoons in our mouths, as it is said of more favored beings in other parts of the earth. If there is any enjoyment to be had by exchanging the wooden spoon for one of genuine argentine character, the sooner it is bartered away, who will, not say it is all for the better?

There is, of course, such a thing as being too fast; of acting in haste and repenting at leisure; but the spirit which seeks to annihilate time and space, and endeavors to compass in the limit of three score and ten the enjoyments of the fabulous term of Methusalah, is undoubtedly the correct one, says Young America.

Most of our successful men start into business life comparatively penniless. Few achieve an independence till their heads get gray; and, after securing a home in some suburb, and baking in the sun under the nineties in summer, and being frozen almost dry by the cutting winds of our arctic winters, who can wonder that such immense sums are annually wasted on "big trees" in the vicinity of all large cities? I have known as much as $100 to be spent on the removal of a single large tree. In the hands of a skillful gardener such grand operations may, and often do, succeed well; but they are, on the whole, miserable and expensive failures. But can nothing be done to cheer our declining years with the shade and shelter our bodily wants petition for? Will not the Landscape gardener's art lower its dignity a little, and in the name of old age, bend a little to its utilitarian spirit? We can enjoy an Italian landscape, in a splendid pic-tare - feast the eye on the delicacies of light and shade in some Swiss mountain; or pity the poor "Laplanders of the North," while enjoying the pleasures of a winter in the Antilles. But our heat, and our cold! Can we enjoy the sight of an iceberg while roasting, and not be allowed "to come within the influence of the frigid luxury? or freezing, feel any pleasure in the sight of a distant fire we may not approach? Then, gentlemen, shade us - shelter and shade us - you may then give us Chatsworth, or Versailles, or anything you please, superior to any of them all.

A little more attention to fast growing trees - and no lofty position of high art need be encroached on either - will do wonders for us.

Most fast growing trees have few or no other recommendations, and many have objectionable points. No one would be willing to exchange an Oak for an Abele, or a Horse Chestnut for an Ailanthus. Yet both these much abused trees are, like some people, very well in their proper places. Most beautiful trees are slow growers, and are undoubtedly, as we are told, worth waiting for; but while they are coming on, why not fill in between with any kind of quick growing trees; and, where shade and shelter is of paramount importance, if they are not thickly planted among slower growing kinds, they ought rather to constitute the entire planting, than to be absent altogether.

The Abele or Silver Poplar, is perhaps the best known of fast growing trees. It is not a desirable tree for a lawn, because of the innumerable suckers it throws up through the grass after it has reached ten or fifteen years of age; but for a street tree, where suckering can do little or no harm, there are few trees better adapted. It will grow well in any soil but a poor one, - in which indeed no street tree should be planted, - or in any situation wet or dry; though, as with all poplars, the former is preferred. Slower growing trees, as Norway Maples, American Lindens, and the various Oaks might be alternated with them, and the Poplars after some few years taken away; immediate shade would then be gained, while eventually to shade would be added beautiful forms and interesting colors.

All the Poplars are desirable for forming immediate shade or shelter. The gray Poplar, (P. Canescens,) however, enjoys with the Abele the reputation of suckering up too freely after its few first years of vigorous growth are over, to be trusted long on the lawn. For use there, to mix with other trees till they grow, or to make rapid screens, nothing is superior to the Virginian or Swiss Poplar, (P. Monilifera,) commonly known in our nurseries as the "Cottonwood," and "P. Angvlata?" It has one fault, however, that it grows too erect, approaching the Lombardy in that respect. This may, however, be somewhat remedied by shortening the top shoots while they are growing, which throws more force into the lowermost ones. I have a specimen so treated, with a head as round as a Linden. The true P. An-gulata, or Carolinian Cottonwood, is naturally a more spreading headed tree, and nearly as fast in growth. I do not think it is in any of our nur-series however, so that the readers of this paper will not be able to avail themselves of any advantages they may possess. I believe the figure in Downing, of the "Cottonwood," accurately represents this species when full grown. Neither of the two species just described are objectionable in the way of suckering.

The Balsam Poplar, (P. Balsamea,) is of very common occurrence, but most undeservedly so. It is a very bad suckerer, very liable to be bored "all over" with worms, and thus is very short lived.

The Aspen section are not bad for much suckering, and they have pretty round heads. They do not grow quite so fast as the Cottonwood, but are very desirable for variety. The P. Grandidentata, or large American Aspen, is the strongest grower; P. Tremttla, the English, the next; and P. Tremu-loides the weakest, though a very pretty grower.

The Willows are all very rapid growing trees, and the common weeping (Salix Babylonica) and the ring-leaved (S. Bab. annularis) well known. I am not over-fond of weeping-willows, but must admit that to most tastes they are very pleasing. Whatever beauty, however, they may possess, is certainly inside of the first fifteen years of their existence, and they may be spared without regret afterwards. The White Willow, (Salix alba) and the Sallow, (S. Russelliana) also grow rapidly to a good size; but I don't like them - they look too marshy; and two years of the "chilis and fevers" in such a spot makes my teeth feel like chattering when I look at them. I can tolerate the S. Vitellina, for its handsome golden bark in the winter time. May I say anything in favor of the Ailanthus? When the worms have destroyed all the Elms and European Lindens, the borers riddled your ashes and locusts, the caterpillars denuded your maples and willows of their grateful verdure, and the smoke and chemical gases well nigh destroyed the balance in your crowded cities, you may be glad to fall back on one you have contemned, that will effectually defy all such enemies.

Of permanent trees, the most rapid growers are undoubtedly the Silver and Sycamore Maples, the Larch, and the Paulownia; and amongst evergreen trees, the Norway Spruce and White and Austrian Pines. 1 may as well remark that much of the rapidity of growth these trees will exhibit, will depend on the soil. In a deep, rich, and rather damp soil, they will grow much faster than in a very damp or poor one.

I ought not, perhaps, to pass over the merits of the English Alder. I have seen this frequently grow ten feet in a season, and besides, the green glossy leaves are very beautiful.

* It is not surprising that our nurserymen have these poplars so confused, when even botanists have led the wav. It appears that before Miehaux came to this country he was familiar with the "Virginian Poplar," as the P. Monilifera of Alton, in cultivation there. Here in its native place it had a different appearance; and. supposing it some other kind, named it P. Canadensts and wondered why "his father and himself, and several learned bolanists, who, like them, had bavarsed the stales in every direction," could not find it. Populus Canadensis, plate 95-and P. Monilifera, plate 96, fig. 2 - of Michaux (J. Jay Smith's edition), belong to the same plant, ana the collonwood of the nurseries, The true Populus Angulata has the branches angled, as well as the "Virginian Cottonwood." The angled branches of the P. Monilifara is probably the reason of its having been wrongly named "Angulata" by the nurserymen. T. M.

[It would be a curious question for a child to ask "Why are the best trees, like the best people, the most scarce?" It would be best answered by the the observation that "soon ripe - soon rotten," prevails throughout nature's operations. Time is necessary to develope those qualities that are most in esteem; vegetation that goes on slowly, produces hardness and durability; good children all die young, was the argument against goodness, of a sad young dog; and few enough, indeed, are the entirely solid characters that obtain maturity, or make the mark in the world that their early growth gave promise of. Poor soil, winds, and insects; blown about by false aims and falser doctrines, the number of us humans who attain solidity and enduring fame is fewer than the trees of the forest. But we are moralizing, when we only designed to commend our correspondent's remarks, and especially that portion in which,he recommends the topping of the Populus Monilifera; the practical result is wonderfully satisfactory. The objection in practice to planting trees that are to be cut down hereafter when their neighbors have grown, is simply that people rarely or never do it; they become attached to their bantlings, and "hate to cut down a tree." Why, in case of crowding, it is the best thing you can do.

It may be dangerous to take an axe into your confidence, but, as in education with the rod, it is possible to spare the axe and spoil all your plantation; use it, however, discreetly. Ed].
