a parcel of dry old straw put on the floor of a horse's stall for him to lie down and rest upon. When a horse comes tired into a stable, fresh litter has the virtue of making him stale immediately. This is known to be a very great advantage to a horse in a tired state; and when the litter is old and dirty, it never has any such effect upon him. If the owners knew how refreshing it is for a horse to discharge his urine on his return from labour, they would be more careful of giving them all means and occasions of it than they do. This discharging after fatigue prevents those obstructions in the neck of the bladder or urinary passages which horses are too subject to. The bladder being often inflamed by the long retention of the heated urine in it, the creature is thus in danger of perishing.
