Rubber hose is often used in making applications of water. At Boston it is a very common method. Three acres may be watered in a day by using a large, open hose, which, with sufficient pressure or pump capacity, will throw 100 gallons a minute. Although this method has been used with great success, it is open to severe criticism. Too much expense is involved in keeping constant attendants, and even distribution is impossible; the water is also applied too rapidly for most soil types; and heavy soils would tend to bake and become too solid were this method followed.
