| CONFIRMATION OF TELEGRAM. HIVES. ROYCAR. DERBY. and JOHNSON. ROLHEADRolls-Royce telegram address. PICCY. LONDON. STILL CONSIDER IT IS NOT THE TWENTYFIVE PERCENT INCREASED STIFFNESS WHICH IS THE CHIEF CAUSE OF COMPLAINT BUT DIFFERENT BACK SPRINGING AND INTERNAL FRICTION OF NEW AND RECENT SUPPLY OF SPRINGS. HOWEVER IF IT IS REDUCE TO TWELVE PER CENT WHICH EXTRA STIFFNESS IS REQUIRED FOR OTHER THAN BRAKE REASONS.SINCE FORTY PERCENT OF THE BRAKING ON FRONT PROPORTIONATE BRAKING TO SPRING WOULD ONLY REDUCE TOTAL BRAKING FOUR PERCENT WHICH WOULD NOT BE PERCEPTIBLE.
