timbers, with investigations aimed at practical means of prevention; the
efficiency of various wood-preserving processes and preservatives.

(7) Pulp and Paper. The suitability of woods and other fibrous mate-
rials for pulp, paper, and fiber specialties; studies in the chemistry and
engineering of pulping and paper-making processes; chemical and physical
studies of pulps and papers.

(8) Silvicultural Relations. Identification of wood; the effect of growth
conditions on the structure of wood; and the relation of the structure of
wood to its properties.

(9) Technical Studies of Wood-Using Industries. Study of the eco-
nomic utilization of wood with a view to eliminating waste; lumber grades
and specifications; methods of measuring, manufacturing, and marketing
logs, lumber and small dimension stock; development of efficient uses of
wood.

The lectures and research are offered by the staff of the laboratory to
both undergraduates and graduates. Several courses on various technical

STUDENT RESEARCH ASSISTANTSHIPS

Students who show unusual ability in research may be appointed as stu-
dent research assistants in this laboratory by the Forest Service or by the
Bureau of Plant Industry, in accordance with the regulations of the United
States Civil Service Commission, at a salary not exceeding $40 per month.
Application for these assistantships must be made to the director of the
Forest Products Laboratory. The number of students thus appointed will
largely depend upon the funds available and the number of suitable prob-
lems taken up by the laboratory for solution. Students may choose one of
the problems as major or minor work for a thesis as part of the require-
ments for a higher degree.

LECTURE AND LABORATORY COURSES

These courses do not supply the needs of students desiring to take up
the study of forestry as a profession. Such students should enter one of
the regular forestry schools.
