Glandular ciliated pit between the mouth and the chin into which the overflow water 0 passes by a pair of gutters, and in which fine particles are aggregated into pellets, which the animal deposits.
Winnipegosis and Manitoba at high water, in spring-time, discharge their overflow through small streams into Winnipeg.
In the heart of the delta numerous large lakes or marshes abounding in fish are formed by the overflow of the Irrawaddy river during the rainy season, but these either assume very diminutive proportions or disappear altogether in the dry season.
There are wart hogs, baboons (maned and maneless varieties), a tree monkey, jumping shrews, two kinds of squirrel, a small hare, rock rabbits 2 It is probable that a divergent branch leaves the Shebeli some distance above the swamps and that at high water an overflow into the Juba occurs (see Geog.
The loose soil on the banks of the river is every year carried away in great masses, and the channel has so widened as to render the recurrence of an overflow unlikely.
In years of exceptional flood the Seistan lakes spread southwards into an overflow channel called the Shelag which, running parallel to the northern course of the Helmund in the opposite direction, finally loses its waters in the Gaod-i-Zirreh swamp, which thus becomes the final bourne of the river.
With further experience it has become obvious that very few reservoirs are capable of equalizing the full flow of the three consecutive driest years, and each engineer, in estimating the yield of such reservoirs, has deducted from the quantity ascertained on the assumption that they do so, a certain quantity representing, according to his judgment, the overflow which in one or more of such years might be lost from the reservoir.
This makes a difference of level, at the outside, of six or seven feet; and yet the water shed by the surrounding hills is insignificant in amount, and this overflow must be referred to causes which affect the deep springs.
During the pope's absence in Paris, at the coronation of Napoleon, Consalvi remained as virtual sovereign in Rome; and his regency was rendered remarkable by a great inundation, caused by the overflow of the Tiber, during which he exposed himself with heroic humanity for the preservation of the sufferers.
The great boundary rivers flow through low-lying valleys fertilized by their overflow or percolation, while a high bank leads up to the central upland, which, though naturally dry and unproductive except where irrigated by wells, has been transformed by various canal systems. This favoured region may be regarded as the granary of upper India.
