racing or under some pressing necessity, the swiftest progress is rarely attained, for it is trying to all parts of the engine and consumes a good deal of fuel, which cannot be bought for a trifling price.

You would be confused by any attempt on my part to give a technical description of all the motor appliances, nor is there need to do so. If you have just bought a motor boat, you will be taught how to control and manage it by a practical instructor, and such instruction is better than pages of directions. To show the truth of what I have just said, I will quote a single paragraph from the description of the boat concerning which I shall have a good deal to say in the course of my story.

"The keel is of white oak, with specially bent elm frames. Planking of selected Laguna mahogany, finished thickness one-half inch, in narrow strakes and uniform seams, secured to frames by copper boat nails, riveted over copper washers, all fastenings being of bronze or copper to withstand salt water. Seams of hull caulked with special cotton payed and puttied. Outside of mahogany planking, finished in natural wood with spar varnish. Watertight bulkheads fore and aft which assist in floating the launch in case of accident. Decks and interior woodwork finished in selected Laguna mahogany. Steam bent quartered oak or mahogany coaming extending around cockpit."

Alvin Landon's launch was thirty-five feet long, with six-cylinder, sixty-horse power motor and a guaranteed speed of twenty-four miles an hour. The motor was placed under the forward deck, where it was fully protected by a hinged metal deck. To become somewhat technical again let me proceed:

All the valves were placed on the same side, the camshaft (operating the valves) as well as the pump shaft being mounted on ball bearings. The crankcase was of tough aluminum alloy, and lubrication was well provided for, being kept at a constant level in the crankcase by a geared oil pump. A gear-driven pump circulated the necessary cooling water for the cylinders, which passed out through the copper exhaust pipe at the stern. Only one operating lever was employed and that was placed directly at the helmsman's left hand. The gasoline tank contained fifty gallons and was under the after deck with a pan below it for safety's sake, draining overboard. The propeller wheel and shaft were of bronze.

Alvin's motor boat, thus partially described, included the necessary deck hardware, "such as brass chocks and cleats, flag pole sockets and flag poles, ventilators to engine compartment, rubber
