What is the ifNfect on radia t r when '.eft standing A. M. Trailers are practical provided the trailer load is not too grea'. *vhu con necting a trailer, care shsould be taken to hitch it to the rear axle, not to the frame. The connections should he dou ble, one to each side, as near th( wheel as possible, y tee* cable in excellent materia, for this purpose.
