Gentlemen: Attention Mr' H' v' scott

August 29,1928.

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

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

The Forect Products Laboratories suggested the uee of Sugar Pine, which we have found to be splendidly worlable and well suited to otr purpose.

We are glad to have found a material with theee properties and we appreciate your cooperetion in hurrying it to us, so t'hat the shipment of batteries could leave with the expedition on scheduled time.
