her claim to originality. The machine to- which the principle is applied ingenious and valuable though it is-is not an absolute nov. city but, on the other hand, this machine is only one of a thousand applications which can be made of the principle. If were allowed to mention the adopted to obtain this result could cover the whole explanation in ten lines the cat would be so effectually out of the bag that every one would wonder that the anil nal had never been released before, and many

 an expert would feel like hanging himself for

 a When 1 knew that had succeeded in ind

 what I had been seeking for by study and

 experiment for fifteen years" said Miss Hos

 mer, 'I first asked the opinion of well-known

 American engineer, Mr. Clarke, a relative of

 Rev. James Freeman Clarke, of Boston.

 asked whether it was possible to accomplish a

 certain result with the permanent magnet, and

 he replied No e.nphatically. By the way,

 this is the question have asked every one of

 the experts to whom I have shown my secret,

 and it is too funny, after hearing their positive

 negatives, to see the expression of their faces when do for them exactly what they have

 just said was impossible. Mir. Clarke having seen the impossible accomplished, assured me that need have no doubts as to the value and importance of my discovery. then came to England, and here have consulted few men

 whose reputations are almost worldwide

 Mir. Newton, of the well-known firm of New

 ton & Hales, told me at once that my question

 involved an impossibility, almost an absurdity, and added: Why, Miss Hosmer, you are

 seeking after perpetual motion, and that has

 made more lunatics than Yes, I know, l interrupted, more lunatics than love or

 religion, but now wait until you see what I

 will show yon' Well, he could scarcely be-

 lieve bis own eyes, and had to repeat my

 demonstration several times Then he made the magnet accomplish the work himself and

 acknowledged that his confidence in the ap-

 parently impossible was quite gone. Hence

 forth he would never say anything was im-

 possible without the qualifying statement 'by

 any known process His partner, Mr. Hales,

 came in, gave the same negative answer to my question, and then dropped down on his knees

 beside the table as he saw me repeat my ex-

 pertinent. These gentlemen and Mr. Brown

 ing, the we1l-known maker of scientific instru-

 ments, are all enthusiastic over my discovery, and are thoroughly convinced as to it's prac-

 tlcabifty'

 Miss Hosmer said further that among others

 who had been shown the new principle applied was Mr. John Penn, Jr., of the well-known

 works at Greenwich, and she had a letter from

 him saying that the discovery actually fright ened him, so great would be the revolution in

 machinery. Professor Tyndall was away in Switzerland, but he had had the principle

 described to him, and in letter from Mrs. Tyndall to Miss Hosmer he enclosed mes-

 sage testifying to the importance and absolute

 novelty of her discovery, and saying that he | should give it careful attention on his return

 to England.

 Mr Browning is now engaged on a four | for | is to be completed this winter, when Miss Hosmer will return here from Rome and have | it publicly exhibited. She already has the offer of unlimited capital for the development | of her invention, and she will therefore escape l the troubles of most inventors. She intends, however, to attempt no large ventures until her own model proves concusively that she

 has a genuine success Immediately after the appearance of the machine in England another

 will be sent to the United States, and Miss | Hosmer will go there to stay at least year. I She has returned to her native land for short

 visits several times since she first came to Flu rope, but this time she says she will stay and

 travel for good long time.

 ga MARBLE FROM LIMESTONE

 my second invention an imitation of mar | ble." '-.e

 ''Is that really an imitation? 1 asked, half doubting my own senses. ''A cannot see 1 wherein it differs from the genuine article," STy,c sc fl.v-o,

 and yet it is an artificial product This mar

 ble-for it really is marble-is made of soft | limestone. You know that in Italy and else | where there have been many attempts made l to turn limestone into marble, but heretofore | they have succeeded only in making scagliola, which, though useful and ornamental in some

 ways, is not generally available for building

 and decorative purposes. The. Marchesi di Campagna made long series of experiments | Ill Rome having special furnaces built for

 heating limestone He regarded marble as l nothing but limestone, which in the molten state of our planet, had become, as he expres- sed it., better cooked He heated the soft Italian limestone in many different ways, us- ing variety of different temperatures and keeping up the cooking process sometimes for number of days Once he evolved it in dry sand, another time in gravel, and at other times he kept the limestone under constant compression; but he was always unsuccessful. l knew all about these experiments, and it oc-

 cured to me that. although dry heat had fail ed, possibly moist heat might succeed. So

 made a number of experiments myself, and from the very first I was satisfied that had found the right theory bfnally hit upon the idea of compression and moist heat together,

 and therefore raised a steam pressure of seven ty-ive pounds. At the end of three hours my

 retort contained marble instead of limestone, and you see some of the results before you" The table was covered with polished slabs

 of white and colored marble There was noth-

 ing about the stone to awaken any suspicion

 that 1t had come from the original quarries in

 the rock-footed hills in any different character from that in which it then appeared.

 .That stone" said Miss Hosmer, ''can be

 used 80 soft as to be easily cut or turned into any desirable shape. Quantities of it can be found in all countries not much harder than chalk. Having been shaped as desired, it is placed in boiler, subjected to steam pres sure of three atmospheres for three hours, and it will then be found to have all the hardness, cOhesiveness and appearance of true marble If color is needed it can be given by putting the color desired into the boiler, using metal colors only to insure permanency. If pure white is desired the limestone is treated to an alum bath"

 SOME USES FOR THE MARBLE. 6 Miss Hosmer's specimens were certainly

 beautiful. They were as perfect marble to all appearances as ever was quarried. Every va riety of color and shade had been used Some slabs were of pure white, others deep black ]; the delicate cream of the antique marble was

 initiated as successfully as if the slabs had been
