The scandals of the past few years have at last moved the yachting world to concerted action in regard to "bat" boat racing. We have been treated to the spectacle of what are practically keeled racing-planes driven a clear five foot or more above the water, and only eased down to touch their so-called "native element" as they near the line. Judges and starters have been conveniently blind to this absurdity, but the public demonstration off St. Catherine's Light at the Autumn Regattas has borne ample, if tardy, fruit. In future the "bat" is to be a boat, and the long-unheeded demand of the true sportsman for "no daylight under mid-keel in smooth water" is in a fair way to be conceded. The new rule severely restricts plane area and lift alike. The gas compartments are permitted both fore and aft, as in the old type, but the water-ballast central tank is rendered obligatory. These things work, if not for perfection, at least for the evolution of a sane and wholesome _waterborne_ cruiser. The type of rudder is unaffected by the new rules, so we may expect to see the Long-Davidson make (the patent on which has just expired) come largely into use henceforward, though the strain on the sternpost in turning at speeds over forty miles an hour is admittedly very severe. But bat-boat racing has a great future before it. CORRESPONDENCE Correspondence Skylarking on the Equator TO THE EDITOR--Only last week, while crossing the Equator (W. 26.15), I became aware of a furious and irregular cannonading some fifteen or twenty knots S. 4 E. Descending to the 500 ft. level, I found a party of Transylvanian tourists engaged in exploding scores of the largest pattern atmospheric bombs (A. B. C. standard) and, in the intervals of their pleasing labours, firing bow and stern smoke-ring swivels. This orgy--I can give it no other name--went on for at least two hours, and naturally produced violent electric derangements. My compasses, of course, were thrown out, my bow was struck twice, and I received two brisk shocks from the lower platform-rail. On remonstrating, I was told that these "professors" were engaged in scientific experiments. The extent of their "scientific" knowledge may be judged by the fact that they expected to produce (I give their own words) "a little blue sky" if "they went on long enough." This in the heart of the Doldrums at 450 feet! I have no objection to any amount of blue sky in its proper place (it can be found at the 2,000 level for practically twelve months out of the year), but I submit, with all deference to the educational needs of Transylvania, that "sky-larking" in the centre of a main-travelled road where, at the best of times, electricity literally drips off one's stanchions and screw blades, is unnecessary. When my friends had finished, the road was seared, and blown, and pitted with unequal pressure-layers, spirals, vortices, and readjustments for at least an hour.
