wheel must be turned round with the same velocity *. In this case none of the power would be lost, because its whole force is perpetually applied at the very point of the lever (b. fig. 2d.) where it must produce its greatest effect. The apparatus is so simple, and the conclusions so indubitable, that mere inspection of the figure is sufficient to convince every person of the most moderate understanding, so that farther illustrations are perfectly needless. ' I shall only just make one remark here, which is indeed sufficiently obvious, that, were a moving power of this sort adopted, it would be as easy to apply it to a wheel placed in the top, as in the bottom of a building, or to one in every stage of it, if necessary.
In this way may be obtained the full benefit of the greatest height of any fall of water, without losing the smallest portion of its weight as a moving power ; a thing that is altogether impracticable by any other means that has ever yet been adopted. Even with regard to falls of moderate height, where a wheel could be made of such a size as to receive the water into buckets, at its full height, much power would be gained by hanging the buckets to a chain in this manner, and making the water, by this means, act always by its whole weight nearly, upon the horizontal or longest lever of the wheel, as at b fig. 2. and no where else. It was from a contemplation of the infinite force that might thus be obtained in the Highlands of Scotland, for turning machinery, that I have

so often taken notice of the amazing advantages which that country enjoys above all others for manufactures, by machinery; nor is this the only advantage it possesses in this respect, as I shall have occasion to show at some other time. While I contemplated these things, which seem never to have fallen under the observation of any other person, it will not be deemed wonderful, if I have expressed myself rather more forcibly on that subject than first they could see reason for,-many things appear paradoxical, when simply announced, which, when explained, are simple and obvious truths.
The above may serve for giving a general notion of the mode of applying water with advantage, for the purpose of moving machinery, where the fall is great. In another paper I shall endeavour to give some general notions respecting the application of water, as a moving power, in every country, where no kind of cascade can be commanded.
DETACHED REMARK. Take care never to provoke enemies by severities of censure; yet suffer not yourself, in defence of a good cause or sentiment, to be overawed or depresa sed by the presence, frowns, or insolence, of powerful men ; but persist on all occasions in the right, with a resolution always present and calm.
Be modest, yet not timorous; and be firm without rudeness.
ODE OF HAFEZ.
[TRANSLATED FROM TNE PERSIAN BY SIR WILLIAM JONES.]
HTHIR, boy, a goblet bring,
It is wine, boy, that can save
Wine's the sun. The moon, sweet soul,
Dash us with this liquid fire,
If the rose should fade, do you
If the nightingale's rich throat,
Be not sad, whatever change
My bright maid, unless it be
Should it chance t'o'erpow'r my mind,
Unto Hafez, boy, do you
SONNET BY MRS CHARLOTTE SMITH.
The Shiv’ring native, who, by Tenglio's side,
Beholds, with fond regret, the parting light
And leave him to long months of dreary night;
Yet knows, that, springing from the eastern wave,
The sun's glad beams shall re-illume bis way,
He waits in patient hope returning day.
Not so the suff'rer feels who, o'er the waste
Of joyless lite, is destin'd to deplore
Which, once extinguish'd, can revive no more :
For tbv Bee.
Enough has been shewn of contempt and d'sdain ;
For 'cis much nobler joy to give pleasure than pain.
Would you charm men of sense, and engage their addresses,
My Chloe of pride, as of painting beware;
And the maid's almost ugly, that only is fair.
For the Bee,
A NEW KIND OF FENCE DESCRIBED.
и a Fences about land are a very expensive and troublesome article to the farmer; whatever, therefore, tends to diminish this expence, and to render the fences more complete than those now in use, will be accounted a valuable improvement.
There are two principal descriptions of fences; walls and hedges. Walls have the advantage over hedges, in being an immediate fence, as soon as they are made ; but they are expensive, and unless made of the best stone and: lime, perishable.
Hedges, on the other hand, cost less money at first, and when they are once completed, they are very durable ; but they require to be long nursed, and carefully tended when young, so that it is many years before the
person who makes them can derive any material benefit from them. It thus happens that they are too often neglected when young; and if this be the case, it is scarcely possible to make them ever afterward a complete fence at all."
I am now to describe a kind of hedge which can be reared at a small expence-is a fence as soon as made, will continue perfect and firm for a great length of time, without needing any repairs ;-and, without rambling too much to damage the crops around it, will afford a greater. quantity of bruth for fuel, or other purposes, than any other kind of hedge now in use.
To effect all these purposes, it will be necessary to prepare, near the spot where the fence is wanted, a piece of rich clean ground, for a nursery, some years before the hedge is intended to be planted; procure, in the month of October or November, a sufficient quantity of cuttings of the t alsam poplar ;-wood of the second year's growth is.
