Questions for reply in coming issue to be received not later tfto?i MONDAY night. H. H. — While the land remains unfenced, all you can do is to clairu. compensation for any actual damage sustained by the trespass of the cattle. Constant Reader, "Waipori.— (l) Yes. (2) It depends on. the- manner in which the injury . was .sustained. It ,could not be termed I'*u1 '*v accident" if the injury arose through .the "irlan 'being of weaker stamina than his fel-low-workers. .. ' Constant 'Readzr. Flag Swamp.- Your neigh - J,bojir has n,o'right to use your laxid for grazing purposes. -See tho answer to "H. H.," W-aipori, above. C. W.— Mt L. O. Beal, jun., kindly replies: — The formula you require is: 10 plus log c minu3 k^L equals tangent c, a beirg the base which in* your case is 12, c being the perpendicular, which in your case is 1, and c l>eing the angle. 10 is a. constant. This works out th© angle> at 4deg 45ft 49m. If you would like the workings of the sum, send an addressed envelope to the editor, or to Mr H. M. Davey, Dunedin. IW. R., Greymouth. — We subjoin the following recipe, given by "Workshop Receipts,'! but cannot vouch for its reliabilny :—"I: — "I made up a. dry battery, which was in use six months for bell-ringing; and although of small size and very simple, it i 3 equal to Iwo Leelanche cells. I cast a slab of plaster of Pans with a little oxide of zinc with it, mixing it with water as thin as I could, for it to set well, and when thoroughly set, I dried it' in an oven ; when dry I soaked it in a strong solution of chloride of zinc; and mixing a spoonful more of plaster with the same solution, I spread it over one side of the slab, and pressed a zinc plate on it before it was set. Then I did the same on the other side, and put on a plate of lithanode, of course leaving one end of each projecting for binding screws. Afterwards I rolled paraffined paper round the whole, and tied it up tight with string. Its simplicity, cheapness, and portability leave nothing to be desired 83 far as bell -work goes, and I think it would be useful for continuous-current work.— A. L." C. H. C, Christchurch.— "\Ve should not advise you to go in for growing sunflowers with the idea of getting seeds for export. At toe present time sunflowet seed in London is worth . only 138 per hundredweight, at which price you could not ship and pay expenses with' any profit to yourself. Pense. — The hen and a-half puzzle is simply a catch. The answer is 28. "TrBSCRnBBR, Balfour.— The Forth bridge is 8295 ft in length ; the Tay bridge 10,612 ft.
