��one dollar a hundred pounds for each hundred miles.

While the war brought about the con- ditions which made necessary the use of motor-trucks over such long hauls, it also has been directly responsible for the success of the

��undertaking dur- ing the winter of 1917-18. Between forty and fifty thousand motor- trucks will be delivered to the government dur- ing 1918. These will be run over- land on their own wheels from the points of manu- facture to the points of shipment on the eastern sea- coast. Close to one thousand of these trucks have already been driv- en overland since the beginning of

the year. The government has demanded that the roads over which trucks have to run must be kept cleared of snow. The states of Michigan, Ohio, Pennsylvania and New Jersey have risen to the emergency and despite the unusual snowball they have kept a clear cross-country highway from Detroit to New York all winter. This has made it possible to operate the Akron-to-Boston trucks with but few interruptions on account of snow for the

One of the 3 • 2-ton trucks of the Akron concern made the 533-mile run between Akron and New York in sixty hours total time and forty-nine hours actual run- ning time, or at the rate of almost eleven miles an hour for the entire journey. It crossed the Alle- gheny Mountains after a heavy snowfall and with the temperature at thirteen degrees below zero. A truck-driver that can accomplish this is no novice, and has to be equal to any emergency.

��See that Your Garage Is Ventilated. It Is Dangerous Otherwise

DURING the exceptienally cold months of the past winter, many deaths by poisoning from the exhaust of gasoline engines were reported from all parts of the country. In most cases the victim^s had been, for some time, in a poorly ventilated or unventilated garage or other room where one or more gasoline engines were running. A careful investigation has estab- lished beyond doubt that death in these cases was not caused by the exhaustion of the supply of oxygen in the air, but by the carbon monoxide, an extremely poisonous gas, which is generated by the incomplete com- bustion of organic sub- stances. It is one mole- cule each of carbon and oxygen combined. Only thorough ventilation will remove the danger.
