��No Double Exposures with This Device

BLESSED if I can re- member," exclaimed Oscar, "whether or not I've wound the film after tak- ing that waterfall a little while ago! I think I'll give it another turn for good luck!"

When the film roll was developed Oscar found a blank next to the negative of the waterfall and a -double exposure in another part of the film.

To put an end to such uncertainty, Oscar — his full name is Oscar Howard Wil- ber, Jr. — has patented a very simple device which may be attached to any film camera at small cost. A flexible rq,d, sliding in a sheath, is so arranged, that after the trig- ger of the shutter of the lens has been pressed down to make an exposure, the front end of the rod is pressed forward by a spring so as to bar the trigger from returning to its former position. To remove the obstacle and make another exposure possi- ble, the receiving roll has to be given another turn, which naturally brings an unexposed film before the lens. By turning the roll the film is drawn over another roll, provided with a disk at one end. That disk has a tooth which engages, at each revolution, the hook at the other end of the flexible rod, pulling it back and thereby re- leasing the trigger of the shutter for another exposure.

This clever device will spare many an amateur photographer the dis- appointment of losing, by double exposure, a picture valued for its happy associations with a pleasant vacation.

��F course Sister Susie's been sewing shirts for soldiers for some time now, and has also been knitting sweaters, socks, scarfs, etc.; consequently she has Still, she must look to her laurels, for there is a valiant host of rivals springing up — the boys are taking a hand. In our illustra- tion is seen a group of Cathedral choir-boys in New York, who have (ostensibly) foresworn horseplay and mischief in the intervals of wait- ing, and are seriously knitting comforts for the soldiers and sailor- boys. They have been properly and thorough- ly instructed and are turning out just as good stuff as their sis- ters do. The boys dis- play a remarkable seri- ousness of purpose in their new task and no longer consider knitting as mere girls' work unworthy of the atten- tion of a manly boy.
