Motorists should exercise greater care and be more c watchful in’ order to avold accidents involving children playing on the edges and in thoroughfares, land motor vehicle commissioner. Commissioner Baughman asserts that it” behooves everybody who operates an automobile to consider the ‘subject Of their greater responsibility in this sort of traffic hazard and to treat the question with careful consideration in an effort to make correct traffic per- formance a part of the daily routine ~of their driving. Going_into the matter in further detail, Commissioner Baughman says: “The nature of a child is of common knowledge. Every one driving a mo- tor car should realize that the child is the one particular creaturs in the world of traffic motion for whom the maximum of care must be exercised at all times. The acceptance of a gown person’s greater responeibility this question from the standpoint of humanity is one angle of the mat- ter. The other angle is the legal as well as the moral responsibility. It has been held time and time again in the courts of the country that when an operator perceives children In his course—that is, 0 near as to be able to get in his way—he is chdrged with an especial care toward them. He is obliged, in other words, to see that he 80 drives his car that they cannot get in its way with a resulting accident.

And in this connection 4t may be pointed ott what would be proper care in dealing with an adult _ may be insufficient in the case of & . child probably * he can accompli child.” Speaking of the legal aspects, Com- missioner Baughman pointed out that this side- of the question was stated clearly in a recent case in Pennsyl- vania: In this case it was set forth that: “When ‘an automobile driver sees a child in a place of danger, or has rea- son to apprehend that it might 'run into a place of danger, it is his duty to exercise such care weuld reason- ably avoid a collision. On_this point the Maryland motor vehicle commissioner said: “Often, children are aggravating, tindoubtedly. They will not step out of the way promptly; they will race with the machine or try to cling to the running board or ride on the spare tire. Knowing this, as he should, the thoughtful. and considerate operator ust assume the burden of extra care for them. Fw must slow down, give warning and take: the entire initiative to stop, if this be necessary to avold an accident. No.operator is safe to proceed upon any hypothesis that the v will take any certain course of action. -To him the child is an object to be avoided, and he should “Too fast” says the comsclentious driver as he slows down from a trial speed of 50 or 60. “Too fast!

" Commissioner Baughman empha- mized these - points with particular force, declaring thfi: “Such driving habits as_ ng through a crowd of children at afrun- controlled speed, depending upon the horn signal for notice to a child to get out of the way-er_be hit, striking & child who has been in plain view, backing without warning and without Jooking, and any form of driving while near children, except such as is gov- erned by extreme caution and conse- quent car control, will be held more and more to be réckless and intoler- le. “The automobile drivér must ac- cept the responsibility that he must Jook out for the child—because the child represents a mentality which cannot look out for itself. There are many instances, of course, where chil- @ren run into moving automobiles or where the operator has no previous knowledge that the child is near. course, in such cases the operator cannot be expected to guard against an absolutely unforeseén contingency. However, caution against the ever- present emergency of a thoughtless child as a possible traffic emergency 18 a thoroughly worthwhile habit to cultivate.” PE T ~ MOTOR CAR PROBLEMS DUE FOR SPECIAL STUDY Beciety of Automotive Engineers to Name Committee to Consider Various Questions. "“Problems of motor vehicle fleet eperation, rapidly assuming greater economic and engineering impor- tance, soon will be tackled by a gen- eral committee to be established by the Society of Automotive Engineers. Study and discussion -of these prob- ms have become a prominent fea- ture of the society’s. work, and the sion to appoint a committee to evote its attention entirely to them was made at a recent meeting of the governing board. This new committee will représent wehicle operation and maintenance sroups. as well as manufacturers’ and ealers’ service organizations. It will formulate policies and recom- mendations regarding research, stand- ardization and production as reiated to_operation and maintenance. In -addition; it will co-operate with * the sections and meetings committees of the Soclety of Automotive Engi- peers in stimulating irterest in these subjects. k: —_——— < Benzol production {n_Germany set ‘new record in 1825, Production by the 35 members of the Benzol Ver. band (cartel) of Bochum amounted to 235,000 metrie tons. every inch of the way up and town and staging partioularly vicious sttuggies at corners. ‘The practice is becoming more and more pronounced at intersections lighted by automatic signals —on Massachusetts' avenue and Sixteenth street. Find the Smooth:Spoty’ Why the engine seems to run so much more smoothly jone.day than another is not always & matter of &t- mosphere, carburetion, engine whims or imagination on the.part of the driver, It is just that the engine is avolding its rough spots. Some en- gines, of course, are so perfectly bal- anced that the average driver finds all spots smooth, - but the average engine has at least one rough spot which_is recognized, however, uncon. sciously as its pilot. It the engine does not seem to be Of | running as well as it did the day before, change the speed a bit. When this advice was given to one motorist he made the mistake of changing the speeds too radically, |which. simply served to bring him to another rough spot, the engine having two rough places in his case.
