flowers in a room is in some way prejudicial to those who sleep therein.
This belief is probably due to the fact, learned at school, that plants give off at night carbonic acid, which is known to be deleterious to health. A recent writer has published the results of some experiments made in a closed green-house, showing how fanciful are these fears. In this green-house there were 6000 growing plants, and the average of three experiments made early on three different mornings after the place had been closed for more than twelve hours exhibited only 4.03 parts of carbonic acid per 10,000. We can judge by this experiment that from one or two plants the quantity of gas given off must be far too small for recognition, and certainly many hundred times less than that formed by a burning taper or given off by one pair of lungs. A CORNER IN ALLIGATORS. by GEORGE ETHELBERT WALSH. "'Gator hides worth three dollars, and big ones four. That's our game, Jed, and we'll make enough in 'gator hunting to get that pony." "You bet, for there's plenty of 'em down in Loon Lake--big ones, too." |
