Practically no splitting was caused by the nails in unseasoned white fir, spruce, or cottonwood. There was very little splitting in seasoned cottonwood. The nails, however, caused a slight splitting in the seasoned spruce and quite a noticeable splitting in the white fir, but not enough in either to cause an appreciable loss. [Illustration: Fig. 2.—Typical 60-pound white fir boxes showing general run of this wood.] CONCLUSIONS Cube Butter in Cold Storage _Boxes paraffined and parchment lined._—White fir and cottonwood can be used in place of spruce for storing butter in cubes, when properly seasoned, paraffined, and parchment lined. Cottonwood is equal to spruce as a butter container. Butter stored in cottonwood boxes for six months had an average score of 0.048 of a point above spruce treated in the same manner. [Illustration: Fig. 3.—Method of lining 60-pound boxes with paper.] [Illustration: Fig. 4.—Parchment wrapped butter in parchment lined box.] White fir may be used very successfully. It scored during the six months’ storage only an average of 0.381 of a point below spruce. In the final scoring, after six months’ storage, none of the cubes packed in seasoned, paraffined and parchment lined containers received a cut directly due to wood flavor. Green or unseasoned white fir, cottonwood or spruce, may impart a slight wood flavor to the butter when packed in cubes, even though they are paraffined and parchment lined. The butter stored in unseasoned cubes scored an average of 0.218 of a point below the butter stored in seasoned boxes with the same treatment. While the average difference was very small, in some cases there was a decided wood flavor which was pronounced enough to affect materially the flavor of the butter. _Boxes paraffined but not parchment lined._—Unseasoned boxes of white fir, cottonwood and spruce, paraffined but not parchment lined are not entirely satisfactory for storing butter. The butter so stored was criticized in practically all cases for wood flavor. Butter stored in white fir boxes scored 0.358 of a point lower than that in spruce boxes, while butter in cottonwood boxes scored 1.071 lower than that in spruce. Storing butter in cubes without parchment lining or in cubes carelessly lined with parchment will cause objectionable flavors regardless of the wood.
