Larg e elliptical, semicircular, or oval stands are used where an extra number of valves are to be con- nected to one hydrant These special forms (figs. 27 and 28) are also used in sandy soil, where it is de- sirable to space the spouts as far apart as possible. If several outlets are set in a small diameter pipe, water will wash the furrows together where they connect at the hydrant. Where the larger sized hydrants are used it is a good plan to set them against a curb or fence, otherwise they will be an obstruction to cultivation if placed in the ordinary manner. These large hydrants are sometimes used where the smaller type would answer as well, but they have their use especially in walnut orchards where a large num- ber of furrows are required between tree rows. The oval type set with the long axis parallel to the tree rows presents the least obstruction to cultivation where the stands can not be placed against a fence or curb. There are orchard hydrants which are covered over the top, with no valve connecting stand to the underground lateral, the amount of water delivered to each furrow being regulated by means of small galvanized gates that are attached to spouts set through the sides of the stand. This type is practicable where heads are low, but where pressure is in excess of a few feet the valves are difficult to make water-tight. Leaves and trash also tend to clog this type of hydrant. In some cases where it is not desirable to place a number of stands, the hydrants are placed a consid- erable distance apart, and portable pipes fitted with outlet valves are Connected fig. 28.—Another type of distributing Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United St
