This food is often recommended without any specific instructions as to what gruel, and unless linseed or other descriptive name is used, oatmeal is understood. It is best prepared by adding the meal to cold water in the proportion of one pound to the gallon. It should be placed over a quick fire, and continually stirred to prevent dry particles from adhering to the bottom and sides of the sauce-pan. As it approaches boiling-point the cook should be more assiduous than ever with his wooden spoon, as there is no food more easily spoilt. As soon as it begins to thicken it should be removed from the fire and emptied into another vessel, and allowed to cool before being offered to the patient. Oatmeal and water is sometimes spoken of as gruel, and is given to horses when severely taxed, or on long journeys when time cannot be spared for a "square" meal. It is both sustaining and stimulating, and when properly prepared very acceptable both to the sick horse and to others when fatigued with a hard day's work.
