A MODERNIZED'WATER CLOCK, An Interesting Arraagwient For tbo Amateur to Try Ui.s Hand At, .. In these - piping” times of unerring pre»Ulon of rate of a timepiece, no one will naturally expect that a mechanism of tins kind should go unfalteringly and absolutely correct. In fact, it will probably require to be treated in conformity with the i: .tjf Contain Cuttle—viz, to “wind it once a jhty..and moVo the. hands forwiu-d r.hout 16 minutes every morning and likewise 1.) minutes ht night, 'and you'll have u watch on which you can roly.” A description of this mechanism, found In a German work, Is given by The Jewelers’ Circular as follows: A thin arbor A Tests upon two, sup- - a s*rnlnrbr. j-jid truly round , ~r. .... . .vrtho purpose

: A WATER CLOCK, v/dl. One of Its ends protrudes beyond the ■dal fastened at SI and carries a hand, •’ho hours only are marked upon the dial, d consequently this the only hand Is i ?ie hour hand. -About In the middle of the arbor A is | filed a pulley, B, with a deep groom Around this pulley la wrapped a thread, ! one end of which carries a cork float, F, while a small center weight is attached to the other end. Exactly underneath the float Is a so called ‘tulip’ glass, which is filled with water to the rim when tho clock Is si.vrted. A conduit, an ordinary cotton wick, M, passes Into an empty cylindrical vessel, R, which stands close by. “Tlie natural consequence ensues. Tho n ick M acts to a certain degree as a siphon, absorbing the water in the glass B ...ul discharging it into tho lower vessel, l:t consequence of this theformor emp-. tic A-iwlv, while tho latter fills gradually. The sicking of tho water level naturally jvudnccß tho same with the float F, there- ), ■ actuating the pulley B, tho arbor A ,d the hour hand C. By a suitably large ~ill<-v, li. the hour hand can be made to involve In mi approximately correct time.” In spite of some difficulties, such as getring a glass of exactly tbo correct shape -ul tho pulley of the rightsize, readers of a mechanical turn of mind may find entert, i union t in endeavoring to construct this < iitatlcn of a clepsydra, or antique Roman water clock. Scrap Steel Boiled Into Shape. A process has been discovered by which •crap steel can bo heated and rolled into •hape, according to an exchange. Tho secret of tho Invention Is a mineral composition, which, blended with certain chemicals and mixed with the scrap, enables tho mass to be heated, rolled and welded without melting. Crosspieces of scrap are placed in layers over a bottom tiuco, and the composition is applied. Finally a top piece la laid on, and tho whole Is strapped together with Iron, making a bundle inches thick, which is heated and rolled into any shape required. A Remarkable Foot In Botany. It Is a remarkable fact in botany that no species of flower ever embraces, In the colors of its petals, the whole range of the spectrum. Where there are yellows and reds there are no blues, when blue and red occur there aro no yellows, and when wo have blues and yellows there are no reds. Tulips come nearer to covering the whole range of the spectrum than any other spe-ck.-s. They can ho found ranging through reds, yellows and purples, but a blue one has never been found, says u scientific Journal The Lavender of Commerce. In parts of England lavender is grow* In largo quantities. Tho leaves and hloiaoma of tho peppermint are put into tho still, but lavender is only extracted from rhe flowers of that plant. Most of the lavender of commerce is grown and distilled In tho south of France, but it Is claimed that no lavender has been produced to equal tho English perfume, and it fetches •lx or seven times tho price of the bflgt French lavender. Tho Whale In Miniature. There seem to bo records of but three specimens of tho pygmy sperm whale having been found on tho Atlantic coast between Greenland and Cape Korn. ~ That many others have been stranded an our coast Is doubtless sure. AwhaleM •mall and resembling as it does a porpblsa If found by an untrained observer, would no doubt be taken fra-the common pearpoise, which Is so frequently seen along

j»yQMT SPEEM WHALE, our New Jersey coast during the*prlnf ami summer months, says Popular Selena* News, in which the following facts are found: Nearly all the specimens have bees f ound in tropical or subtropical seas, th* i 'aol flo and Indian oceans having furnished most of them. It is nob tq bo wondered at that cetacean literature furnishes us little or nothing on the anatomy of this animal when wo consider how few specimens have ever boon found. A specimen waS secured in February, 1894, by the Wistpr institute, University of Pennsylvania, iris a malk weighing 648 pounds, measuring f to* I').-, inches In length andßfeetfojpt* j 0 ,.. posterior to the flippers. Theelto 1> div;. brown In «olor on the back and al> most white on tho ventral surface. This specimen waS found on the beach at Sea Isle City, N.- J. The adult pygmy wMi probably does not exceed 10 feet in length. Bo far vs Lh luiown, it Is most closely W Is. jd to the true sperm whale.

'how' to cut roots. j Witen ana WUui-e to Mafc« Them *iUl Uow to Cara Fop Them. The months of February and March ai the fir-r half of April are best for to mo;.' rr a '.’if’S'of carnations, roses, i coleus, verbenas and Oita r« of similar nature. j A cutting mny be regarded as a plant j dr a-'a veil of its roots, and while engaged j ii: the process of replacing them it must be kept moist and at tbe temperature Cf gonial to its healthy growth. A littJo diffused light Is needed. It is usual to construct the cutting bench on the north si:!e of the greenhouse and partition it off from tbo other side in order . to beep tbo air moro close and damp ' tl in is needed for the growth of the established plants, which delight in full Bcnshmo ami plenty of air The best material in which to plant the cuttings is rather coarse, clean sand oj the porous fiber of the cocoauut. The object is to keep the cuttings damp, with some access of air to their lower ends through the porous nature of the sand 01 fiber The cutting bench should be watered daily in order to keep it moist, and the temperature must be carefully adjusted to tiio nature of tbe plants to be rooted. Hardy roses, verbenas and carnations root best in a temperature of 6n to 66 degrees, while the cuttings of coleus, tea roses, fuchsias and many othei tropical plants do better in a temperature of ten degrees higher. It is better to have the temperature of the sand five degi cos wanner than the air above the bod in order to stimulate the growth of the rums. This bottom heat, as gardeners coil it. is obtained by carrying hot water' or steam pipes under the bed and inclosing them with sheathing boards, or where a cheaper temporary bed is wanted by a “beat" of fermenting horse mail: ire, six or ten inches deep, covered with an inch of dry leaves,on which sis inches 01 sand are placed. This “heat" will cniise a temperature of 00 to 100 degrees a: first, gradually subsiding to 70 de- | g. ees and less, and needs watching at i fi.st to avoid roasting the cuttings. Where a small bed is wanted for cut tings m a common greenhouse where ti e air is too dry u can be obtained by i covering a box of sand with movable tu.sties or panes of glass, and if the tem- | p.-ratnre of the house is too cool the box j of sand can be warmed by placing a lamp under u with suitable precaution* i against tiro. flow to Make Ttrain Croquettes. Mince finely i % pounds of calf’* ; brains Mix with a bunch of herbs, & shallot and an anchory. all chopped fine 1 Add pepper and salt and put in pan ! with one-half pint of white stock. Stew j five minutes. Add yolks of 8 egg*Spread out to cool. Cut in pieces; roll upon a bread covered with crumbs. Dip m egg. then m more crumbs; fry in lard Serve with wine gravy Uow to Transplant the Maple. In sections where the bard maple thrives it makes the most valuable, durable and ornamental shade tree that oaa bo obtained, and usually It oau be had from the adjacent woods for the asking and digging in warmer climates the soft maple is muoh planted. As the foliage of both starts early, they shonTd be transplanted as soon as the ground if free from frost, choosing trees not over 2 inches in diameter at two feet above the ground. Leave on all the roots possible. keeping them well protected from the sun and wind until again sot out. The best success is usually obtained by cutting off all the branches and sawing off the top eight or ton feet from the i ground, covering all side wounds with paint or varnish and tying over the top a cloth saturated with liquid grafting wax Branches will be thrown out on ail snle.N and shun Id any ot them appeal too low remove them, letting all these above a cerium height remain H too thick, the natural growth of the strongest will crowd out the weaker ones To obtain fully developed shade tree.' do not plant them closer than 80 feet. How to Dry Wet Shoe*. When without overshoes you ora caught In the rain, carefully remove all surface water and mud from the shoes. Then, wnile still wet, rub them well With kc rosene oil on the furry side of canton liaunel. Bet them aside until partially ury, then again apply the kerosene. They may then be deposited in s moderately warm place and left to dry gradually and thoroughly Before applying French kid dressing give them a final rubbing with the flannel, still slightly dampened with kerosene, and the boots will bo soft and flexible a# new kid and bo very little afiected by their bath in the rain. Bow to Benefit Without Genuine Massac*. A rubber flesh brush is the next beat i thing to a masaaga A thorough nibbing of the face and neck twice a day is almost equal to facial massaga It does not irritate the skin as a bristle brush floes, and it does exercise every particle of flesh and stimulate the nerves so that «the face loses the strained look which is derived from one set of tired muscles tnd another of unexeroised ones. How to Revive a Person From Fainting. For an ordinary fainting fit lay tbs patient flat Great harm has often resulted from ignorant people trying to make the patient sit up or propping up the head on pillows. To send the blood back from the heart the first posture is absolutely necessary. Let the patient Us bo that the feet are higher than the head, throw the clothes about the chest and throat open, sponge the face with cold water and give some cold water to drink. Novel Car* For Sleepleeenue. Cover your head with the bedclothes and breath and rebroathe the same air. Thus the stimulating oxygen will be redooed, and sleep will soon be won. This is not a dangerous method, for when asleep the coverings will surely bo disturbed, and the necessary fresh air will be respired.
