Wairarapa Age MORNING DAILY. MONDAY, NOVEMBER 7, 1910. MOTOR-SHIPS.

Sir W. 11. White, the great naval constructor, writing on the proposed motorships, says in the Spectator that "For all classes of oil engines ample supplies of air and the free discharge of products of combustion when exhausted from cylinders are essential. As between the operations of a motor on a -car, carried practically in the open, and those of a motor fitted in the enclosed engineroom of a ship, there are radical differences; but in many instances those are overlooked or ignored, and

hence has arisen much misconception. .Although increasing demands for oil as fuel and as the source of motive-power are now leading to a rapid enlargement of supplies and the discovery or utilisation of new sources, there is not as yet an assurance that the supply would overtake tlie demand which would result from the substitution of oil for coal in marine propulsion, and so enable'a reasonable price for oil to be maintained. Attention lias consequently been concentrated on "gas-producer" systems which are designed to obtain large and cheap supplies of gas from comparatively inferior qualities of coal, and to utilise, that gas, in internal combustion engines of suitable, design. These gas-producers have been the sources of motivepciv.ci' u\o.A favoured iu proposals

for motor-driven battleships." A long road has to be travelled before the satisfactory use of internal combustion engines for ship propulsion will be secured.
