Specialist, Fumigation Research

A Contribution from the
Department of Horticulta

April 18, 1935


This bibliography is offered to those interested in the field
of hydrocyanic acid gas fumigation in an attempt to bring together as much
of the literature as possible. Such a work could not possibly be complete
because in many papers the use of the gas is not mentioned in the title and
the reviewer did not consider it important enough to mention in his abstract.

The Review of Applied Entomology, Experiment Station Record,
Chemical Abstracts, Rasch, Frickhinger, Bellio and Wolf furnished most of
the foreign titles. Those not actually reviewed by the writer were checked
from one source to another as far as possible.

Abbreviations are used according to the "List of Periodicals
abstracted by Chemical Abstracts" published by the American Chemical Society
in 1931. Those not included in this list follow it as closely as possible.

The writer would appreciate corrections and additional citations,
which would, as far as possible, be compiled as supplements to this paper.

Papers to which are appended long bibliographies are marked with
an asterisk.

The writer wishes to take this opportunity to acknowledge the
assistance of H. J. Quayle in the preparation of this list.

Complete to October 1, 1934.
