impregnated wi th a gelatinous matter, which g/van it'the proparty of adhering with great firmness to whatever, under water, it is placed against. It is close in its texture, and becomes very hard on !one exposure to the air; but when first dug out is not more difficult to svork than chalk.? The indurated clay-stone, along the Panam?t shore, is also an excellent building material; becoming, .though soft at first, hard on exposure. For facility of working, it ?s generally obtained, where softest, below hi?h-water mark. Besides limestone, are found, in the interior, fi?nt, chalcedony, ?tiasper, iron-stone; and near Gatun, on the river Chagres, a very ne fire-stone, of great use in the coustr.action of kilns, furnaces, .?w?. -Giay and loam earth for bricks are also abundant, and sand to mix with lime in mortar.--?' In a word,' says Mr. Lloyd, �perhaps no part of the world possesses a greater variety of build- ing nmterials, nor more facility in procuring them, than does tl? Isthmus of Panami?.' In the precious metals, however, the pro- vince is poor. In Panamk proper, only two mines are worked, Santa Rita and Peq.ueni, both for gold, but their produce .is insig- nificant. They are m the mountains near Porto-Bello. In Ve- ragua, including Choco, a considerable quantity of gold is obtained by washing, and is reckoned very pure: copper and iron are abun- dant; and tin and mercury are s?id to have been found. But very little capital is embarked in the respective works; ?d ?e wa. shings, in particular, are chiefly in the?laands eithe. r?of a few pro- pnetors of slavrs, who thus employ th_em? or of free Indians who �select what they consider favoumble ?i?uafions, Qc. oapy them with- out paying any rent or acknowledgment, employ one portion of the yeas' in coilec?ng the alluvium from the' bottom of the rivers and pil/ng it up in heaps, a s?cond in washing i?, and the remain- der in selling the produce, and wasting it in finery and excess. The total amount is thus comparatvely small, and uncertain from year to year. The vegetable productions of the Isthmus are most luxuriant; and in the vieour and varieties of its woods it challenges compe- tition? in Mr. Lloyd's opinion, with any other part of the world. The followingis the list found among ?ds noteS,. and he has also del?sit?cl with the Society a c01Jec6on of .specimens of the re,- spe?tive woods.
