[ Wild guesses as to Uio speed of tramcars are often made, at corouial and magisterial inquiries, and not infrequently tho evidenco given in this respect loads to no satisfactory conclusion being arrived at. On Tuesday in tJip Auckland Supreme Court, Mr. George W. Davics, a gentleman who not long njro occupied tho position of Secretary of liailways in Western Australia, and who has had many years' practical experience of vehicular locomotion, gave a formula which may bo of considerable service to those of tlio public who desire to come to fome reasonable estimate of the spead of trams, trains, etc., at any time. He said: One mile per hour equal I yard per focond; 2 miles, 1 yard; 3 miles, 11 yards; •1 miles, 2 yards; .1 miles, 'Ji yards; in miles, r> yards; 15 miles. V. yards. Those figure? are not absolutely fractionally corroot, Mr. Uavie-s said, but for practical purposes they tire "ucar enough." Any-j how, si speed of 20 miles an hour enables the moving body to cover !ij yards in one second. • The fiovcrument o(Rc«; throughout New Zealand will bo closed on Thursday, >,'ovwnber 30, tit Andrew's Day.
