diatcly in contact with the goods, assuming, of course, that the method
of packing and storing the goods is in keeping with the idea of
thorough and efificient air circulation.
It will have been noted that use of the term ventilation has not
been made in any of the foregoing, the term being considered as a
description covering another process.
In the foregoing subject of pure, conditioned air, it is assumed
that the air being circulated is pure and of the correct relative
humidity; in practice, this is, of course, impossible, unless there is
provided some means of keeping it pure and of the right moisture
content. The air is continuously taking up gases and odors from
the goods, as well as changing in moisture content, due to absorption

of moisture from the goods or depositing it on the refrigerating coils,
-thereby becoming impure and with the wrong moisture content, which
will, in the course of time, cause the air to become foul and dangerous
and, in the case of forced air circulation, increasingly so, due to the
ability to distribute dangerous organisms, spores of disease germs,
quickly and effectively, unless some provision is made for keeping it
pure; this is where use is made of ventilation.
Starting out with the storage space clean and free from mould or
objectionable odors, and with the goods in a clean and altogether
suitable condition, the preservation is dependent more upon preventive
measures than upon corrective ones, and it is a very simple matter to
offset or rectify the slight contamination of the circulated air, due to
eliminations from the goods, by some system of ventilation, that is, by
