TÁROGATÓ 13 Meijerin piipusta ei enää nouse savu, kun kirkon tornista kajahtaa temppeliin kutsu. Maitokoneet ovat seisauksissa kun urkuparvesta kaikuu ihana urkujen soitto. Meijerin isännöitsijän paikka kirkossa ei öle koskaan tyhjänä, kun nousee nuori pastori saamatuoliin. Samoin patruunan ja monen muun. Kirkko täyttyy vuosi vuodelta yhä enemmän. Ja kasvaa myös JumaJan sanan tunteminen ja voima. Eikä kukaan kärsi ravinnon puutteesta-Patruuna ja pastori ovat rakkaita ystävyksiä. Kirkko ja maanviljelys löysivät toisensa — maitoparannuksessakin. Oliko tämä vain ihanaa unta! Benevolens. (Kotiviesti) ANIMAL WARMTH It may be news to some of the readers of this article that the greatest bodily heat in animals, as measured in degrees, is found in birds. This fact is the more remarkable when we remember the effect of wind on bodily warmth. As we know, a bird almost lives on the wing, and of course any moving body, especially one with wings, creates some breeze, or greatly adds to any already existing. Wind makes cold far more punishing, yet we énd a flying swallow comfortable and happy in a frigid atmosphere, its bodily temperature 110 or 112 degrees, F. A horse, normally, has practically the same bodily temperature as a man. I once read a story in which a rider dismounted in a storm because the body of his horse made him cold! With a healthy horse, that would never be true—and least of all when the animal was exercising vigorously, as that one was in struggling through deep snow. That writer hadn’t had much experience with horses. The dog’s temperature is 102 degrees, F.— about three and one-half degrees higher than man’s. And the poor dog cannot sweat! He would bum up were it not for the relief brought through respiration. All animals with lungs, including man, cool partially through respiration; but the canine has to depend solely on it. On a hot day when the dog runs you will see him open his mouth, protrude the tongue, and breathe very rapidly to induce more abundant exhalation of moisture. He is said to sweat through the tongue. The size of the animal is bound to have a bearing on its temperature. Unquestionably, a man or a horse has a more powerful heating mechanism than has a tiny mouse; yet the latter’s bodily temperature is 106 degrees, F., as compared to man’s 98-5 The mouse's heating “plant” serves him admirably because the “house” to be heated is proportionately small. Warm-blooded animals endure astonishing degrees of cold. A traveller-naturalist tells of his observation on a fox in Siberia. The weather was extremely cold, yet the animal’s temperature was nearly normal— when the difference between it and the external temperature was seventy-six degrees! Much depends on the eating, and all handlers of animals should remember this particularly in winter. If native to a cold region, naturally clad in fur or plumage, and properly fed, animals stand a temperature of fifty or sixty below and remain well and vigorous, with normal bodily temperature. Fish and snakes have no constancy of temperature to worry about; their bodily heat coincides almost exactly with that of the surrounding medium, water or air. —Canadian Girl. SPIDERS AS WORKMEN Spiders are probably the most indispensable workmen in one of the largest English surveying instrument factories. It is their duty to spin the delicate thread which is used for the cross hairs to mark the exact centre of the object lens in the surveyor’s telescope, states a writer in the New York American. Spider web is the only suitable material yet discovered for the cross hairs of surveying instruments. Almost invisible as this fibre is to the naked eye, it is brought up in the powerful lenses of the telescope to the size of a man’s thumb, so that all defects, if there happened to be any, would be magnified to such a degree that they would be noticed at once and rejected. Human hair has been tried, but when magnified it has the apparent dimensions of a rough-hewn lamp-post. Moreover, human hair is transparent, and cross hairs must be opaque. OUR ENGLISH SECTION.
