What Now? Has the Ocean Broken Loose and a Steamer Lost Its Way?

WE have read of the boat traffic on the streets of Venice, and have seen many interesting pictures, beautiful ladies and picturesque troubadours stepping di- rectly from their doors into their waiting gondolas, but it remained for a Detroit photographer to give to the world a series of pictures of a steamer making its way through the street of a great city and of the ocean lapping the curb of a New York city street.

The pictures were not bona-fide photographs, however, but were the result of a very clever and legitimate trickery, which is simplicity in itself. To secure such a result as the above, he took separate photographs of the street scene and water scene which he wished to be combined. The water scene was then so cut that when placed upon the street scene its edges registered exactly with the curb lines. The water scene was pasted upon the street scene, and a fine spotting-brush was used to cover up any defects. When a photograph was taken of the composite picture thus produced, the above effect was the result. Boys swimming about in the water made the scene still more puzzling. The idea is capa- ble of a wide variety of applications, which will only too readily suggest themselves to the photographic trickster.

��Change Your Motorcycle into a Motor-Raft

NY amount of sport can be gotten from a motor- raft, and for those having a motorcycle, it is a simple matter to make the trans- formation. The engine of a motorcycle is particularly adapted for such work, al- though any similar engine can, of course, be used. The raft shown in the accompanying illustrations was made by J. Dutton, a British soldier, serving in the present cam- paign in Africa. Being of a mechanical turn of mind he made it during the hours when he was off duty. When his vacation came, he spent three weeks in exploring the tropical rivers.

He mounted the one-cylinder engine of his motorcycle near the front of two pon- toons which he made by soldering together a number of tins in which gasoline was supplied. To two eight-foot lengths of these, he soldered a bow and a stern which he formed from other tins. The propeller- shaft is carried under the platform fastened between the tops of the pontoons, connec- tion being made with the propeller through a universal-joint of the kind used on

automobiles.

The raft is light and it

can be easily carried

past falls or from

one lake to another

near it. It is strong

enough to carry

supplies for a

long trip.
