SLOW PROGRESS.
Two snails reposed in a rectangular cardboard box in an unused shed. The box, which had no lid, was thirty inches long and cightec,n vide with a depth of four inches, and was lying proper side up. One of the molluscous sluggards was then hibernating at one end of tho box, while the other was moving from the opposite'end "towards-him, tho incident prompting a problem. Draw two circles of equal" size on the" floor of the box, one at each end, 'so that tho long side as well as the short ones form two • tangents of the circles, tho other long side of the -box being some distance from the circumferences. The sleeping slug was at 'the exact centre of one circle, and its mate was within the oth*r at a point eight inches in a direct line'from one tangent, and nine inches' from the other also in a direct line. It then moved towards the other snail in a direct, line,, resting on the circumference of its own circle. The interesting question for the reader to answer is how long would it take slug No. 2 to reach its dormant brother, starting from the last-named point, if it progressed at tho rate of an fnch in twelve minutes?
