" ABOLISH DELIVERY TRICYCLES," A CORRESPONDENT URGES ; AND THE REASON HE GIVES IS THIS:
" Many years ago, a doctor in Paris, after thirty years' experience in the hospitals, began to classify certain cases of premature breakdown which he had treated. Young men in the twenties, thirties, or early forties, suffering from heart-strain or kidney trouble, attracted, after a time, his special attention.
" Little by little, as he traced the careers of these sufferers, he discovered that nearly all of them had been bakers', butchers' or grocers' assistants, and had driven box tricycles.
"The doctor examined some of these vehicles and found that on an up-gradient the weight increased in terrible ratio—in a proportion that doubled the weight in an up-gradient of five inches in 100 feet.
" A few months of work on one of these tricycles had often done an ill almost irremediable after two or three yew's."
