eraticns probably account for the steel type there and wood in this country.
 Tail-ligl1Us used are noticeably much smaller than formerly. Some of the lamps depend entirely on electric sys- tenS and others are designed for use with kerosene as well. Of course, the usual form of kerosene lamp is still used to a considerable extent for both dash and tail lights.
 Tall tales about gaSo- inc freezing in automobile tanks in the Yukon are all buncomhc, acCtT ding to G. c. Cole, United States ( 'TSul at Dawson City. What causes the most trouble, he says, is the fact that the standard tread of automobi es is too wide for use ip winter, because it is consid- erably wider than the sled tracks, and he suggests that somebody would make a great hit Tn the Yukon by senC;ng up narrow tread cars that would go in the sled tracks.
 When the idea of elective illumina- tion for gasoline vehicles was first conceived batteries were resorted to as 9 current-supplying source, but the shortcomings of this course were rec ogn+ze6 very quickly. The voltage of the average battery output varies II Fer cent. from full charge to dis charge. This f1uctuation in voltage is accompanied by a very noticea ble and disa greeable variation in candle power of an incandescent lamp which is designed for certain voltage This experience caused the engineers to look for another means of car lighting and the construction of lighting dy- namos was laid down as the most de- Sirab1e solution Of the problem.
 The ordinary form of automobile top remains as popular as ever. Most of the rather striking colors. however, which used to be seen in top mater plain black top appears to have been found the most practical as we'll as the most refined in appear rance. The use of canvas and similar materials fry~ fN Eli i'd out, too, giving place to more durable and more slightly stuffs. The vic toria top, adaptable to automohi use from the carriage field, continues in close-coupled cars, though it is some times used on the ordinary touring car.
 Guatemala is the latest country to replace the horse-drawn gun carriage with the up-to-date automobile Dat tie wagon. Three motor cars have been ordered equipped with machine guns, with a capacity of 500 shots a front of the drivers seat. In the body O. the car, which, by the way will be a pony-tonneau on a regu- lar 1912 chassis, there will be a wire less aparatus rigged to a S5-foot mast and dynamo sufficiently strong to transmit a message 50 miles More over, each car will carry balloon for the purpose of carrying the wireless apparatus high in the air, in order to increase it's range.
 Rear-axle construction has not changed to any great extent during the past year outside of the worm drive. The bevel differen iaI Is hold ng it's own and bids fair to do so for some time to come. There are now many American firms, however who are taking up the worm drive and bringing 1t forward, as European man. ufacturerS have been doing for some time. The pressed-steel housing is proving popular and there are some additions to the ranks of those who make this type of rear axle. The accessibility of the axle has also been very notable in the case with which the parts may be reached by removing the cover plate.
 If car is travelling at a speed of about 10 miles an hour a system which Eliminates the road for some 20 feet ahead of the automobile may be quite adequate, since at that rate of pro- pulsion the car may be stopped with out difficulty within a distance of 20 feet If the automobile travels at twice the speed mentioned the mo- mentum Of the car becomes twice what it was at 1C miles per hour it by the same braking efforts will be proportions teIy in excess of the distance needed in the first place. Mod ern automo mobiles travelling at an aver age rate Of 20 miles an hour are equipped with brake facilities capable of bringing them to standstill with in 90 feet, which is enough to avoid mishap UL any kind, if the driver keeps his eyes on the road ahead.
