collapse. Estimates are made of the volume and value of
wood that could be recovered by the introduction of recon-
ditioning to eliminate collapse, especially with E. globulus
and N. dombeyi.

Describes the timber resources of Trinidad and problems
that have curtailed employment opportunities in timber
processing and have led to the dependence of Trinidad on
imported sawn timber. Basic information is given on the
development of logging, sawmilling, seasoning, grading, and
wood preservation not currently used in the country. Possi-
ble changes in the industrial structure for modernization of
the industry are discussed.

Samples of eleven species of woods of commerical value
were collected from Escaracega and Uruapan, Mexico. The
anatomy, uses, and drying characteristics of these woods
were presented. Mechanical tests, including specific gravity,
hardness, static bending, and shrinkage were performed all
on woods. Common and commerical names of these woods
are noted.

Using the Forest Products Laboratory, Madison, Wiscon-
sin, method (1955) and W.T. Simpson’s method (1971) the
equilibrium moisture content (EMC) of wood in 12 dis-
persed Brazilian cities was predicted. A large variation in
the EMC of wood in the various cities was noted. However,
the values of EMC determined by the two methods were
not significantly different for the range of temperatures
studied. While the predicted EMC values are of practical
use, values for the most commonly used Brazilian woods
should be determined.
