The following table affords the result of observations made with the view to determine the relation between temperature and altitude, in these parts.

The Monass is called Goongree by the Booteas; its bed is very much inclined, and tranquil pools are of rare occurrence: it is not fordable in any place, although many of the rapids are not very deep. The singular bridge is said to be of Chinese construction, and that it serves the purpose of a chief thoroughfare, is a proof of the extremely small population of the country.

Onions grow at Nulka, plantains, sugarcane, tobacco.

Bheirs are common. Weeping cypress occurs, but stunted.

The entrance to this village on the north-side, is through a square building, the ceiling of which is painted, and the walls decorated with figures of deities, white and red.

February 6th.—We descended immediately to the Monass, keeping along its banks throughout the greater part of the march; rising however, over one or two spurs that dip into it.
