THE SIX RIVER MOTOR BOYS ON THE ST. LAWRENCE.

It was dark on the St. Lawrence River at nine o'clock that August night. There would be a moon later, but the clouds drifting in from the bay might or might not hold the landscape in darkness until morning. The tide was running in, and with it came a faint fog from the distant coast of Newfoundland.

Only one light showed on the dark surface of the river in the vicinity of St. Luce, and this came from the deck of a motor boat, anchored well out from the landing on the south side of the stream, fifty miles or more from Point des Montes, which is where the St. Lawrence widens out to the north to form the upper part of the bay of the same name.

The light on the motor boat came from an electric lamp set at the prow, six feet above the deck. It showed as trim and powerful a craft as ever pushed her nose into those waters.

Those who have followed the adventures of the Six River Motor Boat Boys will not need to be told here of the strength, speed and perfect equipment of the _Rambler_. The motors were suitable for a sea-going tug, and the boat had all the conveniences known to modern shipbuilders. She had carried her present crew in safety up the Amazon to its source, down the Columbia from its headwaters, through the Colorado to the Grand Canyon, and down the Mississippi from its source to the Gulf of Mexico.
