_Boxes neither paraffined nor parchment lined._—Butter allowed to come in direct contact with any of the three untreated woods will always take up wood flavor. The injury to the flavor is about equal from all three woods. Sixty-Pound Boxes Packed for Market White fir is as good as spruce for 60-pound boxes when seasoned and parchment lined, the butter being wrapped in parchment only. Cottonwood is not quite as satisfactory as either spruce or white fir, there being some criticism on the flavor of the butter. Butter can be shipped in seasoned white fir or cottonwood boxes, lined with ordinary wrapping paper, if the butter is parchment wrapped and cartoned. There is no advantage in using parchment paper to line the box. Since there was practically no trouble experienced in the unparaffined boxes, there is no advantage in paraffining the inside of the box. Since the completion of the investigational work, approximately 40,000 white fir boxes have been used with entire satisfaction for shipping butter at the University Farm.
