The trade winds give rise, in the region most exposed to their influence, to two westward-moving drifts - the equatorial currents, which are separated in parts of their course by currents moving in the opposite direction along the equatorial belt.

Part of this rejoins the North Equatorial Current, and part probably forms the variable Mexican Current, which follows the coasts of Mexico and California close to the land.

Unyoro has played rather an important role in the past (unwritten) history of Equatorial Africa as being the region from which the ancient Gala (Hamitic) aristocracy, coming from Nileland, penetrated the forests of Bantu Africa, bringing with them the Neolithic civilization, the use of metals, and the keeping of cattle.

The mountain chain immediately overhanging it, the high temperature of the sea washing it,,the frequent thunderstorms to which it is subject, the moist atmosphere of its equatorial situation, and the shorter regime of the dry south-east wind are the principal causes of the heavier rainfall on the west coast.

Both are abundantly illustrated in most popular works on astronomy, and it seems sufficient to refer the reader to the original descriptions.2 We pass, therefore, directly to the equatorial telescope, the instrument par excellence of the modern extra-meridian astronomer.

In its simplest form the mounting of an equatorial telescope consists of an axis parallel to the earth's axis, called" the polar axis "; a second axis at right angles to the polar axis called" the declination axis "; and the telescope tube fixed at right angles to the declination axis.

Since the transit circle is preferable to the equatorial for such observations wherein great accuracy is required, the declination and hour circles of an equatorial are employed, not for the determination of the right ascensions and declinations of celestial objects, but for directing the telescope with ease and certainty to any object situated in an approximately known position, and which may or may not be visible to the naked eye, or to define approximately the position of an unknown object.

Coordinates referred to this system are termed equatorial.
