 We Fish for the Clam 

 with Dynamite 



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. 

 Needless to men-
