thod was experienced by the failing of one of the piers of Weftminster Bridge, before it was finished.
The following section on the preparing of timber, will not only serve as a specimen of the performance, but is of such extensive application as to furnish information for land as well as water service:
• We have in Ireland) very little timber now of the produce of this kingdom of any kind, but large quantities of both oak and fir imported; on which two forts, 1 Mall make a few remarks.
Oak is generally allowed to endure all seasons and weathers, better than any other fort of timber, and some people are of opinion, that it is the best of all others in water. I know the pier or piles, which we began to run out in this harbour about the year 1728, have long fince suficiently proved, that it was not by any means ade. quate to that purpose, though I do believe, that there is not any. country that produces better oak timber than ours, notwithstanding those piles rotted and decayed in a very short time ; but whether that was owing to the nature of that particular timber, or to any thing peculiar to our harbour, I know not, but it is reported there is a sort of worms that either breed in or are nourished in those piles, that totally destroy them
• There are, indeed, several methods that have been made use of to preferve timber. Sir Hugh Platt informs us, that the Venetians make use of one, which seems very rational, viz. to burn and scorch, their timber in a flaming fire, continually turning it round with an engine, till it has got a hard black crusty coal upon it.--Others inform us, that the Dutch preserve their gates, portcullis's, draw bridges, sluices, &c. by coating them over with a mixture of pitch and tar, whereon they strew small pieces of cockle and other shells, beaten almost to powder and mixed with sea sand, which incrusts and arms it wonderfully against all assaults of wind or weather; but for my own pari. I conclude, that the Venetian method is preferable, because, I believe, it is the sap that is either in oak or fir, that is the principal cause of their decaying so soon. Besides, that fap probabiy breeds and nourishes the worms that are natural to it, but there are not any worms peculiar to the water that I have ever heard of.
• Worms generally breed in the fap of all kinds of building tim. bers, and have a powerful effect on them, either without or within, doors; and all old and dry soft woods breed them in great abundance, just as mites are bred in cheese ; and some of these worms are a quarter of an inch in length, and near a tenth of an inch in thicknels; and in very sooty old cabbins where soft woods are generally made use of, they are to be found in great abundance. For these reasons, you ought to be exceeding careful how you make use of any sort of lappy timber, but particularly in all works that stand the weather, for the sap is of a corrosive nature, and for that reason ought not to be made use of, especially before it is a little seasoned in any work that requires to be durable.
I know there are carpenters who pretend it is necessary to paint their work direaly, and I admit that in some cases it may; but it
ought to be done with judgment, and not merely to varnish over and hide the imperfections of their work. As the preservation of timber is a subject suitable to our present purpose, I advise you never to paint either greep or (appy timber of any kind.
- When I was building the mansion-house of Ramsfort, one day after dinner, Mr. Ram observed to his company, that he had some time ago, cut up lome of his own fir timber into scantling, out of which he had a great number of field-gates made, and that several of them chat had been hung up near his house, he had painted immediatelv, but those that were at a distance through several parts of his extensive demesne, were not painted; that those which were painted were all quite rotten, but those that were not painted continued firm. The company seemed surprized at this information, and Mr. Ram enquiring of ne the cause of this apparent phænome. non, I readily answered, that the painting of the fappy wood, encrusted and confined the sap, and prevented its being exhausted by the sun and weather, and being continued within it, preyed upon, potrified, and destroyed the hearty sound wood. As to the wood that had not been painted, the sun and weather consumed and exhausted its sap, and thereby rendered it of a proper consistence, and made it well seasoned. It is for this reason I advise againit painting, or otherwise encrusting fappy green wood, unless you have some very powerful reasons for it.
• I once happened in company with a very ingenious gentleman, one Mr. Smith, who was so kind as to communicate a secret to me, which fruck me greatly, and I instantly put it in practice, and am now convinced it is an excellent method to make red fir cimber near as durable as oak, i. e. after your work is tried up or even put together, lay it on the ground with stones or bricks under it to about a foot high, and burn wood (which is the best firing for that purpose) under ii, till you thoroughly heat and even scorch it all over, then, whilst the wood is hot, rub it over plentifully with linseedoil and tar in equal parts, and well boiled together, and let it be kept boiling while you are using it; and this will immediately ftrike and link (if the wood be tolerably seasoned) one inch or more into the wood, close all the poses, and make it become exceeding hard and durable, either under or over water ; and if there should be any fappy parts in it, they will receive such benefit by the fire and heat of this natural and penetrating liquid, that they will also thereby become exceeding durable. Good red fir prepared after this manner, will, for many uses, lalt as long, if not longer, even than oak timber, especially in water; and if good fir timber is con. ftantly kept in water, it will keep fresh and found much longer than oak.
• I have often seen Nating and placering laths, clove out of bog oak and bog fir; in cleaving the fir laths, I frequently observed the turpentine as fresh and firm in it as if it were perfect rofin; and I have heard of the splinters of this wood being used not only for torches, but by poor people sometimes as candles. In the butt of a clean trunk of a bog fr-free, it will split thin and tough like whalebone. It is a generally received notion that the timber trees which are found in such abundance in some of our bogs, have lain there ever fince the great deluge, but be that as it may, the bog oak timber is always found to be frushey, dozed, and short grained, and not near so sound as the fir timber, though both taken up at the same time out of the fame bog. Hence I think we may safely conclude, that red fir timber is exceeding durable, and consequently unexcepcionable as to our present purpose, provided it be kept eatirely under water ; therefore, let us determine to make our coffers of good sound red fir timber, and keep them under water as much as we conveniently can.'
In treating of light-houses, Mr. Semple also recommends lamps instead of coal fires; only he directs the placing them behind glass semi-globes, whereas at Liverpool we find they stand before glass or metal reflectors *.

ART. VI. Know your own Mind: A Comedy, performed at the
Theatre Royal, in Covent Garden. Written by Arthur Murphy,
A Deltouches, it is by no means to be accounted a randas
tion, or to be ranked among the servile imitations of the French drama. An original vein of English humour animates the dialogue; and characters of our own growth are happily introduced, and faithfully delineated, particularly those of Miss Neville and Dalhwould. The last indeed is said to have been drawn after the life, and to exhibit the features of the deceased Aristophanes of the Haymarket. How far this idea is juft, his numerous acquaintance may partly determine from the following specimen of the dialogue :
Enter Lady BiLL, DASHWOULD, and Malvil. • Lady Bill. Mr. Dashwould, do you think I'll bear this? What liberty will you take next? You think, because I laugh, that I am not offended. — Aunt, I received a letter, and he has attempted to soatch it from me.
Dash. Why it brings a little cargo of ridicule from the country, and my friend Malvil lees no joke in it.
MAL. When my friend's name is brought in question, Sir
Lady Bell. It is diverting notwithstanding -Aunt, what do you think? My cousin Cynthia, you know, was to be married to Sir George Squanderstock; her mother opposed it, and broke off the match, and now it's come out, that Me was all the time the clandeftine rival of her own daughter.

} both laugo.
Sir HAR. (goes up 10 BYGrove) And Dalhwould has been fay. ing
Byg. Po! repeat none of his favings to me.
Lady Bell. Did you say any thing, Mr. Dashwould? What was it?
Dash. Oh! nothing. Sir George Squanderstock is my very good friend.
Mal. And for that reason you might spare him. No man is without his faults.
Dash. Ay, allow him faults, out of tenderness.
Byg. Sir George is a valuable man, Sir, and represents his county to great advantage. DASH. He does fa ; takes a world of pains ; nothing can escape Aim ; Manilla ransom not paid; there must be a motion about that matter : he knots his handkerchief to remember it.-Scarcity of corn! another knot-triennial parliaments-(knots) Juries judges of law as well as fact (knots) national debt (knots) bail in criminal cases (knots) and so on he goes, till his handkerchief is twisted into questions of state : the liberties and fortunes of all posterity dangling like a bede roll; he puts it in his pocket, drives to the gaming table, and the next morning his handkerchief goes to the wash, and his country and the minority are both left in the suds.
Lady Bell. What a description !
Mrs. BROM. (afide to Millamour) How can you encourage him? Let us leave 'em to themselves.
MAL. You see, Mr. Bygrove
Byg. Ay! thus he gets a story to graft his malice upon, and then he sets the table in a roar at the next tavern.
Sir Har. Never be out of humour with Dalwould, Mr. By: grove ; he keeps me alive; he has been exhibiting pictures of this fort all the morning, as we rambled about the town.
Dash. Oh! no; no pictures ; I have shewn him real life.
Sir HAR, Very true, Dashwould: and now mind him : he will touch them off to the life for you.,
Mrs. BROM, Millamour so close with Lady Bell! the forward im. portunity of that girl. (afide, and goes to Millamour.)
Dash. There is positively no such thing as going about this town, without seeing enough to split your fides with laughing. We called opon my friend Sir Volatile Vainlove: he, you know, shines in all polite assemblies, and is, if you believe himself, of the first charac.. ter for intrigue. We found him drinking Valerian tea for his breakfast, and putting on false calves.
Sir Har. And the confusion he was in, when we entered the room!
Dash. In the next street, we found Jack Spinbrain, a celebrated poet, with a kept mistress at his elbow, writing lampoons for the news-paper ; one moment murdering the reputation of his neighbours, and the next a suicide of his own.- We saw a young heir, not yet of age, granting annuity bonds, and five Jews and three
Christians, duped by their avarice to lend money upon them. A lawyer
Sir Har, Hear, hear ; it is all true. I was with him.
Dash. A lawyer taking notes upon Shakespeare: a deaf Nabob ravished with music, and a blind one buying pictures. Men with. out talents, rising to preferment, and real genius going to a jail.-An officer in a marching regiment with a black eye, and a French hair dresser wounded in the sword arm. Sir Har. Oh! ho! ho! by this light I can vouch for
every word. Byg. Go on, Sir Harry, ape your friend in all his follies; be the nimble marmozet ; grin at his tricks, and try to play them over again yourself.
Sir Har. Well now, that is too severe : Dashwould, defend me from his wit. You know I hoard up all your good things.
Dash. You never pay me in my own coin, Sir Harry: try now; who knows but you will say something?
MAL. Friend or foe it is all alike.
Lady Be' l. (coming forward) And where is the mighty harm ? I like pulling to pieces of all things.
Mil. (following Lady Bell.) To be sure it is the life of conversation. Does your Ladyfhip know Sir George Squanderstock's fifter?
Lady Bell. I have seen her.
Mic. She is a politician in petticoats ; a fierce republican ; the talks of the dagger of Brutus, while the settles a pin in her cucker ; and says more about thip-money, than pin-money.
Byg. And now you must turn buffoon?.
DASH. I know the lady; the scolds at the loyalists, gossips againft the act of secilement, and has the fidgets for Magna Charta.
Mil. She encourages a wrinkle against bribery; Airts her fan at
Enter Miss Neville, and whispers Mrs. BROMLEY.
Exit Miss NEVILLE.
[Exit. Byg. No, Sir, I fhall not leave the enemy in this room behind me: a bad tranllator of an ancient poet, is not so sure to deface his original, as his licentious frain to disparage every character.
DASH. Sir Harry, he will neither give, nor take a joke.
[Steals out. Mrs. Brom. (afide) Millamour gone!
[Exir. Byg. Let me tell you, sir, with all your flashes of wit, you will find that you have been playing with an edge-tool at lait. And what does this mighty wit amount to ? The wit in vogue, exposes
