number of orders for such machines which is being received from many overseas countries. The number of good performances with which these demonstration six-wheelers are credited has just been added to by the successful accomplishment of a tour by one of the maker's A3-type models through the mining districts _t.of the Province of Quebec, the information relating to the run having been received from Thornycroft (Canada), Ltd.
Six-wheeler versus Tractors.
The run commenced from Maniwaki, which is the terminus of the C.P.R. railroad, and it was arranged in conjunction with many concerns operating in the district, who were interested to have an opportunity for observing the vehicle's capabilities. In all, seven of their representatives accompanied the lorry, which brought its load up to a total of approximately 2i tons.
This part of Canada is devoid of made roads, and, hitherto, tractors have been employed during the summer months for taking up the necessary food and supplies to the mining camps. These vehicles, weighing 7 tons unladen, have made their own trails which, having no proper bottom, are for most of the year up to a foot deep in thick mud. There are, furthermore, numerous holes and occasional rocks, and these, in consequence of the rigidity of the tractors, have, we are told, been responsible for many breakdowns. It was, therefore, hoped to emphasize the economic value and merits of sixwheeled vehicles if, as was anticipated, they could succeed in overcoming the transport difficulties of the district.
In the early stages severe conditions speak, he day's, performances of the Thornycroft six-*heeler were discussed, and everyone freely acknowledged its capabilities. The next morning another route was chosen for the return journey to Maniwaki. The road conditions on this stretch were even worse and at times the ground was so uneven that the front wheels of the Thornycroft sixwheeler were in the air, but it ploughed through the mud and water entirely on the traction of the rear bogie, What the Demonstration Proved.
In comparison with the tractors employed the six-wheeler had, we are told, put up an average of more than twice their speed for less than a quarter the consumption of petrol. The trial proved a complete success and is expected to yield several orders from the engineers of the concerns interested.
