The operating speed of the tug should, ideally, range from about 1/3 mph to 3 mph. The slower speed would permit careful boom- ing along the shore and the starting of heavy loads, while the faster speed would permit rapid traversing of the bog without a load. To achieve this range in speeds it will be necessary to have a transmission with a 4H:1 ratio between high and low speeds and an engine speed range of 2:1 from full throttle to idle speed. Aircooled, one or two cylinder, 4-cycle engines, normally have the 2:1 range. However, the lawnmower or tractor that is avail- able may not have the A^A:\ range. In that case the sacrifice in speed should be made at the higher speed. It is necessary to be able to operate at the slow speed to prevent overrunning of the berries by the boom. Figure 4 is a photograph of the assembled drive components of the tug before they were mounted on the 4'x 10' float. The construction of the drive-wheels and their frame- work is quite clearly visible. The drive-wheels should have \Vi" square cleats to provide traction. The method devised for steering the barge is also relatively apparent. A metal band is shown wrapped around each rear wheel of the lawnmower. The band is anchored to the framework just in front of the wheel. From the point of anchorage, the band passes around under the wheel and then up over the top
