Another date (January 10, 1910) may verify details of such a sybaritic soak in the sea as is to be indulged in only in the tropics and remote from the turmoil of man. Between noon and 3 p.m. the thermometer hanging on the wall of the house under the veranda, five feet from the corrugated iron roof, wavered between 89° and 90°, while the unshaded sun registered 98°. My noontide bath failed to detect any difference in temperature between air and water, and putting my perceptions to scientific test found the sea to be heated to 90°. With the bulb buried in the sand six feet from the edge of the water, the mercury rose to 112° in a few seconds and remained stationary. It being far more blissful to lounge in the sea than on the veranda, I sat down, steeped chin deep in crystal clearness, warmth, and silence, passively surrendering myself to a cheap yet precious sensation. Around me were revealed infinitely fragile manifestations of life, scarcely less limpid than the sea, sparkling, darting, twisting--strong and vigorous of purpose. Tremulous filaments of silver flashed and were gone. No space but was thickly peopled with what ordinarily passes as the invisible, but which now, plainly to behold, basked and revelled in the blaze--products of the sun. Among the grains of sand and flakes of mica furtive bubblings, burrowings, and upheavals betrayed a benighted folk to whom the water was as a firmament into which they might not venture to ascend. Sought out by the sun, translucent fish revealed their presence by spectral shadows on the sand, and, traced by the shadows, became discernible, though but little the more substantial.
