The resin which the various species produce exudes from wounds or gashes made in the bark: but I was told that the trees secrete it also spontaneously from the base of the trunk within, and that large lumps are found in the earth amongst the roots when a tree is uprooted by storms. In the resin, ants and other insects are sometimes embedded, precisely as they are in amber, which substance the Jutahí-síca often resembles, at least in colour and transparency.

Whilst we were at the mills, a Portuguese trader arrived with a quantity of worm-eaten logs of this cedar, which he had gathered from the floating timber in the current of the main Amazons. The tree producing this wood,
