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. I pitched badly twice in an upward rush--solely due to these diabolical throw-downs--that came near to wrecking my propeller. Equatorial work at low levels is trying enough in all conscience without the added terrors of scientific hooliganism in the Doldrums.
[We entirely sympathize with Professor Mathews's views, but unluckily till the Board sees fit to further regulate the Southern areas in which scientific experiments may be conducted, we shall always be exposed to the risk which our correspondent describes. Unfortunately, a chimera bombinating in a vacuum is, nowadays, only too capable of producing secondary causes.--_Editor_.]
VIGILANS--The Laws of Auroral Derangements are still imperfectly understood. Any overheated motor may of course "seize" without warning; but so many complaints have reached us of accidents similar to yours while shooting the Aurora that we are inclined to believe with Lavalle that the upper strata of the Aurora Borealis are practically one big electric "leak," and that the paralysis of your engines was due to complete magnetization of all metallic parts. Low-flying planes often "glue up" when near the Magnetic Pole, and there is no reason in science why the same disability should not be experienced at higher levels when the Auroras are "delivering" strongly.
