MADISON, WIS., April 5.—The next short course

the U. S. Forest Products Laboratory here,
with sessions of instruction in the kiln drying
of lumber following it from June 14 to June 25.
The schedule is arranged to enable those who
wish to do so to take both courses on one trip
to the laboratory. Several double enrollments
have already been made for the June course.
The gluing course is for executives, foremen
and others from shops or factories where glued
wood products are manufactured and for those
making or selecting glue and gluing equipment.
The characteristics of different glues and
methods of gluing the common woods are
points covered in the gluing course. Demon-
strations are given in mixing different kinds of
glues and in making and testing glued joints.
The kiln drying course is given to executives,
foremen and kiln operators engaged in the
artificial seasoning of wood in the wood-using
industries.
