of 1500 minus 18 gall<strong>on</strong>s. It is not very difficult to choose the better<br />

<str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g> with these figures at hand.<br />

The <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g> <strong>on</strong> these tanks is exposed to the rain, sleet, snow<br />

and all kinds of weather; c<strong>on</strong>sequently, <strong>on</strong>ly <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g> that is n<strong>on</strong>absorptive<br />

of moisture should be used, even though an attempt is<br />

made to waterproof it. The Armstr<strong>on</strong>g's <str<strong>on</strong>g>Cork</str<strong>on</strong>g>board applied at the<br />

stati<strong>on</strong>s menti<strong>on</strong>ed above remains in excellent c<strong>on</strong>diti<strong>on</strong>. The felt<br />

at <strong>on</strong>e of the stati<strong>on</strong>s already appears to be coming loose. This<br />

work was installed about eleven m<strong>on</strong>ths ago, May, 1917. Provided<br />

care is exercised to keep the weatherproofing in good c<strong>on</strong>diti<strong>on</strong>, the<br />

Armstr<strong>on</strong>g's <str<strong>on</strong>g>Cork</str<strong>on</strong>g>board will l<strong>on</strong>g out-last the felt and although the<br />

first cost is slightly greater, its superior insulating value al<strong>on</strong>e makes<br />

it by far the best m<strong>on</strong>ey investment.<br />

INTERIOR FINISH OF COLD STORAGE ROOMS IN<br />

HOTELS.<br />

The proper c<strong>on</strong>structi<strong>on</strong> of cold storage rooms for hotels is a<br />

highly important matter. The rooms must not <strong>on</strong>ly be efficient from<br />

an <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g> standpoint when they are new, but they must retain<br />

this efficiency over a period of many years. Then, too, the design<br />

must be correct in order that the rooms give satisfactory and ec<strong>on</strong>omical<br />

service in the proper handling of perishable foods.<br />

These items involve proper <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g>, proper placing of cooling<br />

coils and correct bunker c<strong>on</strong>structi<strong>on</strong>. Positive circulati<strong>on</strong> of air at<br />

all times is necessary to maintain temperatures sufficiently low to<br />

protect the stores, and to prevent c<strong>on</strong>densati<strong>on</strong> of moisture <strong>on</strong> walls<br />

and ceilings which would so<strong>on</strong> result in damp, moldy c<strong>on</strong>diti<strong>on</strong>s so<br />

fatal to many items included <strong>on</strong> the hotel menu.<br />

Aside from these c<strong>on</strong>siderati<strong>on</strong>s, however, practical experience has<br />

taught that some interior finishes over <strong>cork</strong> <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g> are satisfac-<br />

tory for hotel c<strong>on</strong>diti<strong>on</strong>s, and some are not. It must be borne in<br />

mind that these cold storage rooms receive a great deal of abuse,<br />

so to speak, and the interior finish that would be quite satisfactory<br />

for a cold storage warehouse, for example, is entirely unsatisfactory<br />

in hotels where rooms are small and doors are opened and closed<br />

repeatedly throughout the entire day. The influx of warm air each<br />

time doors are used carries with it a certain proporti<strong>on</strong> of water held<br />

in suspensi<strong>on</strong>. As it comes in c<strong>on</strong>tact with chilled surfaces this<br />

water c<strong>on</strong>denses. Unless this warm air is carried directly up over<br />

cooling coils by an active air circulati<strong>on</strong> in the room, it will c<strong>on</strong>dense<br />

<strong>on</strong> walls and stores. While correct design of the interior arrangement<br />

of hotel cold storage rooms is a reas<strong>on</strong>able safeguard against<br />

damp, moldy c<strong>on</strong>diti<strong>on</strong>s, yet some little moisture is always likely to
