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.
