by SUGAR PINE

You will be interested to know that your Sugar Pine was used by us in making battery boxes for Commander Byrd's Antarctic Expedition.

The dry batteries were used for the power supply of five small radio transmitters in planes, on dog sleds and at bases and intermediate stations. A light weight but very strong box material was therefore necessary. Because of sleet and snow conditions a lumber that would not warp, twist or shrink was required. The low temperature demanded good thermal insulation.

The Forest Products Laboratories suggested the use of Sugar Pine which we have found to be splendidly workable and well suited to our purpose.

'We are glad to have found a material with these properties and we appreciate your cooperation in hurrying it to us, so that shipment of batteries could leave with the expedition on scheduled time.

Very truly yours,

BURGESS BATTERY CO.,
