The younger readers of Amateur Work who may be able to use woodworking tools fairly well, and it is assumed that all are in possession of the tools more commonly used, will find the making of the doll-house here described excellent practice in fitting and giving much pleasure to the maker as well as to his younger sister, who will welcome it as a Christmas present par excellence.

The general dimensions are 22 in. across the front, 18 in. deep, 18 in. from the base tothe eaves, the roof being 6 in. higher. A visit to the family grocer will usually be productive of several boxes made of clear pine about 1/4 in. thick ; those in which spices and seeds are packed serving nicely. The cost will not be great, however, if lumber is purchased of a lumber dealer, in which case get whitewood or pine 1/4 in. thick, about 15 feet 9 in. wide being needed. Also, for the floors, 6 feet of 1/2 in. stock 9 in. wide will be needed.

The general design is shown in the drawing and is made as one would make a plain box, after marking and cutting out the spaces for the doors and windows. The back of the house is made detachable, so that when playing it may be laid aside, opening the whole interior at the rear. In marking out the doors and windows, have them of rather large size, that observers or others of sister's playmates may participate in the play. A fret saw will be found handy for this work, but lacking one bore holes in each corner end use a key-hole saw, smoothing up the rough edges with a sharp knife or file. The joints of the hip-roof must be bevelled, and some fitting will be necessary to get good joints. The piazza is added after the rest of the work is done. It is all then mounted on a flat board 24 x 20 x 3/4 in. Hinges for the front door can be made of cloth, or taken from a cigar box, certain kinds of the larger sizes having small brass hinges on them-The windows are plain pieces of glass, fitted in ab. bets cut along the edges of the openings with a chisel if a nice job is desired, or held by tacks, if time does not permit of the other way. The sash markings are done with a tube of dark green paint and a small brush, thinning with oil or turpentine. The balance of the tube is then made quite thin with oil and used for the roof of the house and piazza. The latter work is not done until the body of the house has been painted, the color being as desired by the maker ; a 10 cent can being quite large enough for the whole house.

The interior partitions are made of pieces ol large cigar boxes or similar thin stock, the stairs requiring the thinnest obtainable. The size and step of the stairs are 3/4 in. each. Round tooth picks or matches are used for the stair posts The sills to the windows are also made from thin t: k, as well as the floor and roof of the piazza. The front door is panelled by cutting down with a narrow chisel or carving tool, a glass bead put on with an escutcheon pin serving for a door knob. A similar arrangement at the side can be made to press against a thin strip of brass, closing a circuit and ringing an electric bell, the cell from a night lamp battery and a small "buzzer" completing the outfit. The chimneys are made of strips of cigar boxes wrapped with red paper, and the bricks marked out with white paint or white India ink. if one has a drawing pen, fastening in position only when completed.

Should the reader desire a more pretentious house, one twice or three times the size given can be made, and other features can be added, such as electric lighting from miniature lamps with current supplied from the home main or by battery,

According to Sven Hodin, the explorer, the Chinese invented the process of making paper. On one of his journeys to the interior of China he found evidence that paper of a very fair quality was in use by the Chinese in about 275 A. D. There is a mill. standing in the province of Chilitung where paper was made in 289 A. D., and in the village of Langtikiang, in a suburb of Canton, the ancient town of Kwangtiu, Mr. Heddin discovered a hand mill where paper was made from tree leaves several hundred years before Christ. But this process was very expensive, and the product was used only by the very wealthy. He secured one ancient document written on paper made in this hand mill. The date of the document is 346 B. C, figuring on the time of the Chinese calendar.

Some surprising results are said to have attended a series of investigations made by a medical man in the mining districts of UpperSilesia. The curiosity of the doctor was aroused by the fact that among the many illnesses prevalent in his district lung diseases occupied proportionately a very low place, and that consumptive persons on coming to reside near the coal mines recovered their health after some time without any special cure. These facts he is prepared to verify by statistics. The cures are attributed by him to the coal dust contained in the atmosphere, which he alleges has a drying and disinfecting influence on tubercle development in the lungs. It is now proposed to erect a sanitarium for consumptives in the district referred to, in order practically to test the efficiency of the new cure.
