If only 1 cement-coated nails areused the package is weakened: this was also the case with smoothnails, even when 5 were used. The use of 6 cement-coated 3-pennynails slightly increases the rigidity of the case, an important fea-ture in safe transportation, since distortion of the case soon causesbreakage. The same added rigidity is noticed when wire bindingis used around the sides and bottom of the case at the ends; likewisewhen the lid is nailed in the center. 1 The tests were made in cooperation with the Forest Products Lahoratory. of the P. of Agriculture, and the Bureau of Standards, of the P.
