170 SCIENTIFIC PRESS. [March 16, 1872. = Som ESTIC Economy. Wood Fires. We often wonder why in an age abounding in inventions for household comfort, the oldeet and heet of all—the wood fire on the hearth —has almost disappered. It cannot he on the ground of its greater expense, for that it is hut a trifle compared to luxuries we see everywhere. Scrupulous housewives, we helieve, object to it as untidy. But from such pharisaic regard for the outside of the cup and platter may we be delivered? Now, in the first place, nothing keeps the air of a room so fresh and sweet as an open wood fire. Its advantages in point of healthfulness over ordinary ways of warming is immense. For a room of ordinary eize in this climate it gives amply sufficient heat. And what a wonderful promoter of cheerfulness it is? It ie as much hetter than the open coal fire as that ie better than the hlack hole in the floor called a register. Its voice, as its purrs and crackles and roars, te enough to drive away the worst fit of the blues, Its mounting flames give the cheeriest light in the world. The depths of its glowing coals coutinually allure and charm the eye. There are are not many human beings who are as good company for every mood. Afthe day’s work and fret it brings calm and cheer. It wiles away ail troubling thoughts. If.the mind ie at work, ite unobtrueive companionship soothes and aids. When one ie weary, he may find restful occupation in watching the freaks of the flames, and lietening to their changeful voice. It brightens people and brings them together. ‘To what sceues of friendship and eocial enjoyment doee it lend a unique charm! It is the luxury of luxuries, a thing without which life is incomplete.—Beecher. Iranian Caroxen Satap.—Make a dressiug in the proportion of the yolks of three hard hoiled eggs, ruhbed fine, oné salt. spoonful of salt, one of mnetard and one of cayenne pepper, one of white sugar, four table spoonfuls of salad oil, and two table spoonfuls of vinegar. Simmer this dreesing over the fire, hut don’t let it boil. Stir constantly while over the fire. Then take a sufficient quantity of the white meat of cold chicken for thie quantity of dressing or increase in this proportion to the deeired quantity; pull the white meat into small flakes, pile it up in a dish and pour the dreseing on it. Take two heads of fine, fresh lettuce that. have been washed and laid in water, take out the hest part, cut it up and arrange in a heap or around the chicken, heaped in the middle of the dish, and on the top of this ridge place the white of eggs, cut in rings, and laid in the:form of a chain. A portion of the lettuce to he helped with each plate of chicken. Loox Most ro Your Spgsnpine.—No. matter what comes in, if more goes out, you will always be poor. The artis not! in making money, but in keeping it; little expenses, like mice in a harn, when they are many, make great waste. Hair hy hair, heads get hald; etraw hy straw the thatch goes off the cottage; and drop by drop, the rain comee in the chamher. A harrel is goon empty, if the tap leaks but a drop aminute. When you mean to eave, hegin with your mouth; there are many thieves down the red lane. The ale jug is a preat waste. Inall other things keep within compass. Never stretch your legs farther than the hlankets willreach, or you will soon he cold. In clothes, choose euitahle and lasting stuff, and not tawdry fineries. To he warm isthe main thing; never mind the looks. A fool may make money, hut it needs a wise man to spend it. Remember it is easier to huild_two chimneys than to keep one going. If you give all to back and board, there is nothing left for the savings-bank. Fare hard and work hard while you are young, and you will have a chauce to rest when you are old. A ReviReD Barer’s RECEIPTEOR Breap. Take an earthen vessel larger at the top than at the hottom, pnt in one pint of warm water, one and a half pouuds of flour, and a half pint malt yeast; mix well together and set away in a warmplace until it raisee and falls again, which will bein from three to five houre. Then put two large spoonfuls of salt into two quarts of water and mix with the above rising; then put in ahout nine pounds of flour aud work it well; let it rise until night; then make it into loaves. New andrunny flour requires onefourth more salt than old and dry flour. Bake as soon as light. Preserved Meats. The Victoria Meat Preserving Company (Limited), of Melbourne, hae succeeded in overcoming the difficulty which has hitherto heen experienced in importing uncooked meat from the coloniee to this country in euch a state as to render it both wholesome and palatable food, Their process is very simple. The meat is first slightly corned, theu packed in a tin case, after which melted fat is poured over it, and, the interstices heing filled up,.a tin lid is soldered down—thus effectually excluding air and preventing decomposition. The cooked meats of the same company are also particularly worthy of commendation. A prejudice has been long existent against Australian preserved meats—aud not altogether without reason, for hitherto they have heen eodden and ‘‘done to rags;” hut we are enabled to testify that the samples now supplied are not overdone, and consequently retain all the nutritious properties of freshly-cooked meat, and are equally agreeahle to the eye as they are grateful to the palate, Thefat (by which, as arule, meat may he fairly judged) is not melted into tallow, asis usually the ease, hut is sweet and good; whilst the jelly within hespeaks the qnality of the flesh which it surrounds. The meat ie packed in various couvenient-eized tins, aud is supplied to the trade at a cheap rate. Taking into consideration that the meats are boneless and already cooked, consumere are enabled to effect a eaving of nearly 50 per cent. as againsted hutcher’s meat, and with this inducement to purchasers, 2 little effort on the part of retailers is all that is required to remove the objection to this class of food, and not only would the public be supplied with a most wholesome article of diet, hut a profitable trade might also be firmly established. To Maxe Breap From Fruour tHat Runs. Put what flour you need in your pan, and pour enough boiling water over to just wet all of it, but not to make it thin; sprinkle in a teaspoonful of salt and a epoonful of hutter; stir it up with a large wooden spoou until eure that all the flour is scald‘ed; then cover, and let it stand till cool enough to add the yeast. Sothat the yeast is sweet and lively, you can uee any kind you prefer—hakere’ or home-made. When the flour ie eufficiently cool clear to the bottom add your yeast, and give the whole mass a faithful kneading, adding more tepid milk or water, if needed. Knead till the dough cleane from your hands easily; then eet to rise. When very light, knead again, put into the pane, and leave it to riee once more; then bake as directed above. By this method “running” flour can often he conqnered, and bread thus scalded will be found uncommonly sweet and tender. ’ Bean Soup.—With all thy dinner getting get soup. Get into the hahit of having it. Soupie to a dinner what an anthem is to a divine service. It ie not half the trouhle that -inexperienced housekeepers imagine it may he, Only alittle is required on which to begin a dinner. When once in the way of having it, regularly, you will appreciate the convenience of soup stock, and value it equally with prepared fruits. To make bean eonp, clean the heane over night, pour boiling water over-them and let them stand until morning. Then placein plenty of fresh water and put over the fire; add a small piece of corned heef with half as much pork; cover tight and skim as needed. ‘When the heuns are partially cooked, add sliced carrot, parsley, celery and pepper; boil elowly until done; strain into tureen and cover.—Moore’s Rural. CautTionary.—We ehould let our water pipes run a minute before we take water to drink, or use for cooking in the morning; and in going into a new house, or into one in which water pipes have heen just placed, it is hetter not to use the water for drinking or cooking for at least a month. And on returning home after eome weeke’ ahsence, in summer excursions or for other reasons, take the same precautions, Perhaps in these things we find the reason of some persons eickening and dying just after getting into new houses. RaiseD Crust For Prs.—Some persons cannot eat rich paetry, and for their henefit I willgive aplain recipe. Take one pound of flour, three ounces of butter, one tableepoonful good yeast, and milk to form a dough. Rub the butter in flour, add the milk and yeast, and set to rise. When light, roll out pretty thin, and line the plates. Putin the fruit, roll out the ceyer, and set the pies in a quick oven. This makes a good crust. Good Advice. Many good people are much troubled hy the multiplicity of duties, especially in household matters. They see so much to he done, that they are ever in a worry and hurry, and thus are in danger of doing nothing well, and also leaving many things undone. In ‘their eagerness to do the great things of their calling, they are apt to overlook what seems to he the smaller concerns, which perhaps lie just at hand. They are looking ahead and aloft, and pass over what really ought to he attended to, and which, if attended to and thus put out ' of the way, would lead on naturally and quietly to greater works. These little things may be indispensahle to the accomplishment of the greater. the little stones which together make up the building. They may be the first rounds of the ladder, leading up to loftier hights of achievment. Now let such persons consider what the great German poet, Goethe, eaid—and he hardly uttered a wiser one—‘‘Do the thing that lies next you.” Be it little, do it. It may be great in its necessary relation to something else. Neglect not the preeeut, the immediate thing. The person who adopts this rule will do a world of work a world of good. He will heginat home, in his little circle, and so branch out as each day gives uew and, perhaps, wider opportunities. Cuicken Jetuy.—For chicken jelly, take a little chicken, cut it up into emall pieces; hruise the bones and put the whole into a stone jar, with a cover that will make it water-tight. Set the jur in a large kettle of boiliug water, and keep it hoiling for three hours. Then strain off the liquid, and season it slightly with ealt, pepper and mace, or with loaf sugar and lemon juice, according to the taste of the person for whom it was intended. Return the fragments of the chicken to the jar, and eet it again in a kettle of boiling water. You will find that you can collect nearly as much jelly by the eecond hoiling. This jelly may be made of an old fowl. To Kimn Lroz.—In every issue some one is inquiring how to killlice. Having had six or eight years’ experience with lice on human as well as hrute creation, I find nothing like salt. Wash horses, colts, cows or calves with a hrine ae strong as it can be made. Itie a dead sure shot.—P. Green, Bath, N. Y. Mechanical Hints, How to Use Grindstones. 1st.—Don’t waste the stone hy running it in water; hut if you do, don’t allow it to etand in water when not in ues, ag thie will cause a eoft place. 2d.—Wet the stone hy dripping water on it from a pot suspended ahove the etone, and etop off the water when not in-use. 8d.—Don’t allow the etone to get out of order, but keep it perfectly round by use of gas pipe, or a hacker. 4th.—Clean offall greasy tools hefore sharpening, as grease or oil destroye the rit. & 5th.—Observe: When ‘you get a stone that suite your purpose, eend ® eample of the gritto the dealer to select by; a half ounce eample is enough, and can be sent in a letter hy mail.—Franklin Journal. Brown Tint For Iron snp StEEL.— Dissolve in four parts of water, two parts of crystallized chlorine of iron, two parts of chloride of antimony and one part of gallic acid, and apply the eolution with a eponge or cloth to the article, and dry it in the air. Repeat this any number of times, according to the depth of color which it is desired to produce. Wash with water and dry, and finally rub the article over with hoiled linseed oil. The mnaterial thns receivee a brown tint and reeists moisture. The chloride of antimony should he as little acid as possible. To Draw A Corve.—A plan hut little known among draughtsmen, and most efficient for drawing fair curves, is the following: Cut a strip of soft pewter similar to that used for covering bar counters, ahout one-sixteenth of an inch thick, and from one-eighteenth to three-sixteenths of an inch wide, the length of the longest curve required. Dress it straight, and smooth the edges with a file. By drawing the etrip through the closed fingers of the left hand, or over the thumb, a very regular curve may be obtained, which can be altered at will till it matches the line to be drawn or copied. For fiue or quick curves a slighter strip should be used.—Cabinet Maker.
