An infusion of hay made by pouring boiling water upon it, and covering it up till cool, has been recommended as an excellent nutritious drink for sick horses, and also for those in health. It might perhaps be a very good substitute for gruel; possibly a quart or two of the tea might not be a bad thing for a racer, given between heats, and toward the end of the day, when the horse is beginning to get exhausted from fasting, but it has not been tried.
