A MODERNIZED WATER CLOCK. An Interesting Arrangement For the Am- ; atcur to Try Hla Hand At. In thesis“piiung*' times of unerring pro- i tißlcm of rate of n timepiece, no one will naturally expect that a mechanism of this . kind should go unfalteringly and absolute- ; Jy correct; In fact, it will probably re- ! quire to bo treated in confortnlty with the j advice of Captain Cuttle —viz, to l- wlnd | It once a day and move the bands forward about 16 minutes every morning and likewise 15 minutes at night, and you'll have A Watch on which you can rely.” A description of this mechanism, found In a Gorman work, is given by The Jewelers’ Circular as follows: “A thin arbor A rests upon two supports, S Sl—a straight and truly round knitting needle will answer the purpose

A Remarkable Fact lu Botany. It Is ft remarkable fact in botany that HO species of flower over embraces, in tho colors of Its petals, tho whole range of the spectrum. Where there are yellows and teds there are no blues, when blue and red occur there uro no yellows, and when we have blues and yellows there arc no reds. Tulips come nearer to covering the whole range of tho spectrum than any other species. They can bo found ranging through mis, yellows and purples, but a blue one has never been found, says a scientific journal. Tho Lavender of Commerce. In parts of England lavender Is grown in large quantities. The leaves and blossoms of tho peppermint are put into tha still, but lavender is only extracted from tho flowers of that plant. Most of tho 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 six or seven times the price of the best French lavender. The Whale In Miniature. Theta seem to bo records of but thus* specimens of the pygmy sperm whale having been found on the Atlantic coast botween Greenland and Cape Horn.

HOW Y\j \>o i tv.<o .o.

1 When and WU-re U ill alio Th».m fusC I Ilovy to Care For Thom. ! The months of February ami Marc* and the first half of April arc best fui rooting cuttings of carnations, chrysanthemums, colens, verbenas and others of similar nature. A cutting may be regarded as a plant deprived of its roots, and while engaged in the process of replacing them it must bo kept moist and at the temperature Congenial to its healthy growth. A little diffused light is needed. It is usual to construct the cutting bench on the north Aide of the greenhouse and partition it off from the other side in order to keep the air more close and damp than is needed for the growth of the established plants, which delight in full sunshine and plenty of air. ! The Taesl material in which to plant the cuttings is rather coarse, clean sand or the porous fiber of the cocoauot. The object is to keep the cuttings damp, with some access of air to their lower ends through the porous nature of the sand or fiber. The cutting bench Should 1$ watered daily in order to keep it moist, and the temperature must bo carefully Adjusted to the nature of the plants » be footed, fiardy roses, verbenas snu carnations root best in a temperature of 60 to 56 degrees, while the cuttings ol coleus, tea roses, fuchsias and many other tropical plants do better in a tempera hire of ten degrees higher, it is better to have the temperature of the sand five de- * grees warmer than the air above the bed in order to stimulate the growth of the roots. This bottom heat, as gardeners call 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 “heat” of fermenting horse manure, six or ten inches deep, covered with an inch of dry leaves, on which six inches of sand are placed. This “heat” will cause a temperature of 90 to 100 degrees at first, gradually subsiding to 70 degrees and less, and needs watching al first to avoid roasting the cuttings. Where a small bed is wanted for cuttings in a common greenhouse where the air is too dry it can be obtained by covering a box of sand with movable sashes or panes of glass, and if the temperature of the house Is too cool the box of sand jean be warmed by placing a lamp under it with suitable precautions against fire.

How to Make Brain Croquette*

How to Transplant th« M«pl«.

In sections where the hard maple thrives it makes the most valuable, durable and ornamental shade tree that can be obtained, and usually it oau be had from the adjacent woods for the asking and digging in warmer climates the soft maple is much planted. As the foliage of both starts early, they should b« transplanted as soon as the ground is free from frost, choosing trees not over 3 % inches in diameter at two feet above, Che ground Leave on all tho roots possible, keeping them well protected from the sun,and wind until again set out. The best success is usual ly obtained by cutting off all the branches and sawing off the top eight or ten feet from the 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 all sides, and should any of them appear too low remove them, lotting all those above a certain height remain. If too thick, the natural growth of the strongest will crowd out tho weaker ones. To obtain fully developed shade trees do not plant , them closer than 80 feet

How to Dry IV«t Shota,

When without O.ershoes yon are caught in the rain. carefully remove all bui face water and mud from the shoes. Then, while still wet, rub them well with kerosene oil on the furry side of canton flannel Set them aside until partially dry, then again apply the kerosona They may then bo deposited in a moderately warm place and left to dry gradually and thoroughly Before apply mg French kid dressing give them a final rubbing' with the flannel, still slightly dampened with - kerosene, and the boots will be soft and flexible aa new kid and be very little affected by their bath in the rain.
