NEW sc BMARINE BOAT

While the British government Is
bonding the Holland boats the French
government has made extensive expert
snents with the latter. In their expert

ninety miles on the return making 35C

The Lake model, which is likely to be

are used two on each side, which steer
the boat either up or down. The hydro
