The U. S. Dept, of Agriculture has

published a 38-page booklet titled "Evaluation of Shipping Containers for Western Lettuce."� Data compiled by the marketing-research div. of USDA's Agricultural Marketing Service indicate that a limit of l½ lbs. of lettuce per 100 cu. in. of space offers the most economic use of fibreboard shipping containers. To arrive at this conclusion, the researchers tested light, medium and heavy packs of lettuce shipped in small, medium and large containers. When less than l½ lbs. of lettuce were packed in 100 cu. in. of space, bruising averaged under 3%, but space waste was excessive. More than l½ lbs. of lettuce in the same space resulted in bruising of from 5% to more than 10% of the pack. Copies of the booklet (which contains a number of photographs, charts and tables) can be purchased at 25 cents each from the Superintendent of Documents, U. S. Govt. Printing Office, Washington 25.
