March 20, 1929 The Pittsburgh Box Company, 2722 Smallman Street, Pittsburgh, Pa. Gentlemen: I am herewith giving you an order to supply at the laboratory of Paleontology in the Carnegie Museum, Pittsburgh, the following boxes made like those which we last ordered from you, of the same material and manner of construction. The list of measurement is that of inside of the boxes, as was the case in our former orders: Please let us have these boxes as soon as possible, as I wish to make a speedy shipment of the material which they are intended to contain. I presume your rate will not differ from the rates that you quoted to us, from the order we gave you a short time ago, in which you supplied us with thirty-six boxes in the same style. Very truly yours,
