this particular compound. Hence, when it comes 

 in contact with fire, the caloric so destroys the 

 chemical affinity of this compound, that it is at 

 once resolved into its elements; its hydrogen and 

 carbon immediately become inflamed. — P/tila. Dol-

INTERESTING INFORMATION. 



1. Why does coke burr, without smoke? Be 

 cause it is the distilled coal remaining in the retorts 

 after the above process, and is consequently freed 

 from all gases and vapors. Dr. Amott observes, 

 that "a pound of coke produces nearly as much 

 heat as a pound of coal ;" but we must remember 

 that a pound of coal gives only three-quarters of a 

 pound of coke, although the latter is more bulky 

 than the former. 



2. Why is a man jumping from a carriage at 

 speed, in greater danger of falling, after his feet 

 reach the ground? Because his body has as much 

 forward velocity as if he had been running with 

 the speed of the carriage, and unless he advance 

 his feet as in running, he must as certainly be 

 dashed to the ground, as a runner whose feet are 

 suddenly arrested. — Amott. 



3. Why are serpents said to leap? Because 

 they fold their bodies into several undulations, 

 which they unbend all at once, according as they 

 wish to give more or less velocity to their motion. 

 The body of some serpents is thrown by the mus- 

 cles into a very rigid state, when irritated ; in 

 which condition it breaks into fragments by the 

 slightest stroke. 



4. Why does a horse in the circus lean to the 

 centre ? Because, when the horse moves round 

 with the performer standing on the saddle, both the 

 horse and rider incline continually toward the cen- 

 tre of the ring, and the inclination of their weights 

 counteract the effect of the centrifugal force. 



5. Why is the robin the last bird that retires in 

 the evening? Because its fine large eyes are fitted 

 to receive all, even the weakest rays of light that 

 appear. The worm is its food, too, and few that 

 move upon the surface escape its notice. 



6. Why was the chameleon formerly said to 

 feed on air? Because its lungs 3re very large, and 

 by expanding them, the animal can, at pleasure, 

 make itself appear large or small. 



7. Why does the sting of insects not only pierce 

 the skin, but leave considerable pain? Because 

 the sting is hollow, and conveys the irritating or 

 poisoning fluid within the wound, from a peculiar 

 bag. 



8. Why do bubbles rise on a cup of tea when a 

 lnmp of sugar is dropped into it? Because the 

 sugar is porous, and the air which filled its pores 

 then escapes to the surface of the tea, and the 

 liquid takes its place. 



9. Why is British oak more durable than that of 

 North America? Because variable weather, as in 

 Britain, conduces to firmness, whereas the hot 

 summers of North America impoverish its growth. 



Premium Apples. — Dr. Walker presented to 

 the Hampshire and Hampden Society, at their 

 Show on the 8th of October last, some apples of 

 the Rhode Island Greening variety, sixty of whieh 

 made a bushel. They were from a tree budded on 

 a seedling, and supposed to be only eight years 

 from the seed.

GREEN PAINT. 



A majority of your readers are more or less in- 

 terested in the use of green paint. I will there- 

 fore give you the component parts, as manufactured 

 by some large establishments in our principal cities, 

 and sold as genuine. To be sure when first applied 

 it is a beautiful green, but soon fades, and whitens 

 out, as might be expected, when you are informed 

 that one of the principal ingredients is lime. 



To make Paris Green. 



The body is Arsenic. 



To color, use Blue Vitriol. 



To set, Baromit. 



To make Verdigris Paint. 



For a body, . . . Good Thomaston Lime. 



To color, . . . Blue Vitriol and Baromit. 



To set, .... Alum and a little Salt. 

 Put up in tin cans, and marked, 



33T " Pure Verdigris Paint." jg 



This costs, per pound, to manufacture, about 12 

 cents, and retails at about 40 cents. 



To make a green paint "that is paint," pulver- 

 ize Verdigris. First prime with a lead color; then 

 two or three coats of Verdigris and Linseed Oil. 

 This will last an age. To freshen the color, once 

 in eight or ten years apply a thin coat of linseed 

 oil. 



A durable and cheap paint for barns and out- 

 buildings is an 



Invisible Green. 



To 5 measures of French Yellow mix 1 measure 

 of Lampblack, with Linseed Oil applied raw, with- 

 out boiling, or any spirits of turpentine, which the 

 painters will object to, especially if they work "5y 

 the job.''' 1 Oil used in a raw state dries slow, but 

 will wear much longer; and the spirits of turpen- 

 tine is used to make the paint spread easy, and to 

 dry quick. But it kills the life of the paint, in pro- 

 portion to the quantity used ; as may be observed 

 by examining the knots in a pine board, — the pitch 

 Kills, or eats up, the paint. 



One measure of Venetian Red added to the above 

 invisible green, makes a very handsome paint for 

 out-buildings, and we think the colors look none 

 the worse, as they fade.

WHITE GRAFTS. 



Dear Sir : — I have been trying some time to 

 get a native white grape in my garden, and have 

 had several sent me that were called so, by friends 

 in different parts of the country, but they have all 

 but one, and that nearly so, turned out to be more of 

 a brown or brick-dust color, with, to me, a dread- 

 ful musty flavor. Will some one of your corres- 

 pondents give the desired information. 



Truly yours, R- Lowe. 



New York, Dec. 1, 1851. 



Moore's Rural New-Yorker, is a capital pa- 

 per. It is published at Rochester, one of the most 

 beautiful cities in the country, is printed well, is 

 judicious in its extracts and subjects for editorials, 

 and opens rich like a honey-comb, having sweets 

 in every cell.
