    This is a description of the composition of a forest in Puerto Rico almost unique in that it probably had not received human modification. It comes from a 1948 inventory of 4,570 hectares of what today is the El Yunque National Forest in the Luquillo Mountains. The inventory, preparatory to a forest management plan, was a search for sustainable level of timber volume utilization. The data presented are from 40 apparently undisturbed 1/10 ha samples out of 914 inventory plots along parallel transects. The description covers structure and composition of the two most prominent forest associations. This forest, essentially never humanly modified was distinct from the forests generally over the island today.
