[Illustration: FIG. 84.--Ruins found in Mound No. 40. These consisted of broken-down walls about 2 feet high, joining each other at right angles. Of the wall _A-B_, 10 feet remained standing; of the wall _B-C_, 8 feet. The shaded space included between the walls was covered with hard smooth cement, which had been broken away to a rough edge at its outer border and was continuous at its inner border with the stucco which was still partly adherent to the walls. The walls themselves were built of blocks of limestone (squared on their outer surfaces but rough within), rubble, and mortar; they were nearly 2 feet thick. The long diameter of the ridge pointed almost due east and west. An excavation was made in the cement floor, and at the depth of 18 inches, at the point marked _D_, a single interment was brought to light.] MOUND NO. 41 Mound No. 41 was situated in the northern district of British Honduras, about 9 miles from Corozal. It consisted of a circular wall or rampart varying from 4 to 10 feet in height, inclosing a space 30 yards in diameter. The wall was built of earth and blocks of limestone, and in places had become considerably flattened out from the action of the heavy tropical rains of this region. To the north an opening or gap existed about 10 yards across. Excavations were made in the encircling wall of the inclosure, and also in the central space, but nothing except fragments of pottery was discovered. Mounds of this kind are found throughout the area, though not in great numbers. Some of these are circular or horseshoe shaped, some crescentic, and others curved or even straight ridges. As a rule they contain nothing except a few potsherds, which would naturally be picked up with the earth of which most of them are made; in some, however (especially in the straight ridges), superficial interments have been found. These mounds were probably used as fortifications, the circular, horseshoe-shaped, and crescentic mounds being particularly well adapted to this purpose.
