Tb87: Delivery Costs Per Package On Wholesale Milk Routes: A Comparison Of Two Methods Of Cost Allocation, Nicholas E. Flanders, Homer B. Metzger
Technical Bulletins
This study of milk delivery operations was undertaken to develop labor relatives for different packages and to compare unit costs of delivery computed by using these relatives. A principal issue was whether variable direct labor was a better measure than total direct labor for allocating costs to various packages. Delivery operations on milk routes were timed to determine the amount of labor used in performing various functions in serving wholesale customers. This route information and the financial information on dealer delivery operations comprised the data base for the analyses.

The response of waterfowl populations to marsh management on the Moosehorn National Wildlife Refuge in eastern Maine was evaluated. The objectives were (1) to estimate populations of breeding waterfowl in 1974 and 1975 and compare these numbers with trends of the past 30 years and (2) to interpret these trends in relation to vegetative and other environmental changes that have occurred. The long-term trend of black duck numbers on the primary study areas was downward. Fluctuating water levels, advanced plant succession and a decrease in the number of open-water areas were factors contributing to the decline. Breeding populations of ring-necked …

The scientific literature is filled with conflicting reports on the development of the common scab disease of potatoes and its causal organism. One unresolved question is soil reaction, once thought to be the answer in controlling this disease. Scientific studies an d practical experience over a long period had shown that acid soils having a pH of approximately 5.3 or below usually did not support common scab development, though sporadic and unexplained reports of disease occurrence in these soils were observed. In the late 1950s, however, such reports became more frequent in Maine and before the mid-1960s, losses relate d …
