In August, 1935, the good folks at Science and Mechanics reported on this remarkable caterpillar-tractor "ferry" that took holidaymakers in Bigbury, Devonshire, a quarter-mile out to sea to the Burgh Islands. If only all ferries were like this.
NOT a boat, but a caterpillar-tractor car, is this public utility, located at an English seaside resort. As shown, it holds its passengers above the waves, while picking its way over the bottom. A 24-horsepower engine operates it.
