At Yalloch, just across the Guatemala boundary line from Choro, a small village in the western district of British Honduras, the Alcalde made a remarkable discovery a few years ago. While hunting for a gibnut he traced one to a hole in the ground; on poking a stick into this hole, he was astonished on withdrawing it to find that he had brought out on its end a small painted pottery cylinder. The hole on being enlarged proved to be the entrance to a _chultun_, one of those curious underground chambers cut in the limestone rock found throughout Yucatan and the northern part of British Honduras, especially in the neighborhood of ruins. This _chultun_ contained numbers of fragments of very finely painted and decorated pottery vases, together with two complete cylindrical vases, an ovoid vase, and a pottery cylinder without bottom. Some of these were within the _chultun_, some in a pit sunk in its floor, from which at a later date several pieces of beautifully decorated pottery were taken. The pit had evidently been used as a burial place, in which the memorial pottery was deposited with the body. Merwin found similar painted Maya vases some years later in a chamber covered by a mound, at Holmul, within a few miles of Yalloch, and at Platon, on the Mopan River, a sepulchral _chultun_ was cleared out in which human bones still remained. (Pls. 23-28.) Near the point where Blue Creek or Rio Azul joins the Rio Hondo, in the northern district of British Honduras, is situated in the bush about 100 yards from the latter river a small circular lagoon, of a deep blue color and considerable depth; from this flows a narrow stream, also deep blue in color and highly impregnated with copper, which opens into the main river just below the mouth of the Rio Azul. The little lake is bounded on its eastern side by an almost perpendicular cliff of limestone, in which are several small caves and one large cave. The interior of one of the smallest of these caverns, situated near the base of the cliff, not more than a few yards in depth, was roughly hewn out so as to form shelves. Upon these were found several hundred small binequins of incense, varying in size from 3 to 4 inches in length by 1-1/2 to 2 inches in breadth, to 8 to 10 inches in length by 3 to 4 inches in breadth. The incense was composed of the gum of the white acacia mixed with various aromatic substances; when burned it gave off a very pleasant odor. The gum had evidently been poured while in a liquid state into small bags, made of palm leaves, as in some of the binequins considerable fragments of the palm leaves were still adherent to the copal, and in all, casts of the leaves were left on the soft surface of the gum before it solidified. The binequins which the present-day Maya Indians manufacture as receptacles for their homemade lime, though vastly larger, are precisely similar in shape, construction, and appearance to those their ancestors used as receptacles for copal.
