A CLAM cannot come out of its shell. Its home is on the low sandstone ledges, into which it bores by means of its sharp shell, to a depth of six or eight inches.
The little pholas or boring clam is a great delicacy on the Pacific coast. Its meat is juicy and tender and is excel- lent in chowder. Con- sequently, fishermen are not content to dis- lodge the clams slowly with pick and crowbar. ^ They use dynamite, one ~ blast of which dislodges hundreds of clams.

��For a Perfect Private Secretary, There's Your Watch
IF you have a thousand things to remem- ber this coming week, let your watch be your secretary. Not your ordinary watch, however, but the one designed by W. F. Tubesing, of Milwaukee, Wisconsin.
A dial, rotating once in twenty-four hours, takes the place of the hour and the minute hands. Seven concentric rings marked upon the dial correspond with the seven days of the week. The radial lines on this dial divide off the hours of the day.
On Monday, a stationary pointer on the watch is ex- tended until it lies over the outermost circle. Early on that morning, you mark within the time lines, the cor- responding engage- ments for the day. Then just glance at your watch and you will be reminded of each appoint- ment in due time.
��The Pig Subway and Why It Was Invented
THE feeding barn of a Pennsylvania farmer is used to feed cattle on one side and hogs on the other. In going from the "cattle side" of the house, to their own, the hogs had to pass through the alley in which the farm hands served the feed into the different troughs. The hogs would stop in this alley and try to reach the large piles of corn in the bins before con- tinuing on to their pens. Many diffi- culties would result. To do away with this loss of time and energy, the pig subway was in- vented. A small tunnel, about two feet square, was dug under the alley. Now the hogs must go through that.
