Quote:
The normal city horse produced between fifteen and thirty-five pounds of manure a day and about a quart of urine, usually distributed along the course of its route or deposited in the stable. While cities made sporadic attempts to keep the streets clean, the manure was everywhere, along the roadway, heaped in piles or next to stables, or ground up by the traffic and blown about by the wind.
This of course for cyclists of today would be a great advantage, back then when riding bikes it used to adhere to sides of rims and stop breaks from gripping, sling off tyres all over your back, stick to shoes make roads slippery and traction impossible used to put the wind up when going round corners at full pelt and the back end slid out.
