In this case we suggest that a link should be attached between the outer end of the supporting tube and the frame, to take the reaction of the longitudinal steering tube. The third suggestion is that the box is insufficiently strong for the road shocks received by the longitudinal tube, in which case it only seems possible to make it in another material such as the aluminium bronze suggested, but one would naturally be anxious not to do this because of the increased weight and the greater difficulty of obtaining a die casting which the design specially calls for.
