This paper is a summary of the alternatives studied for the new large seagoing ferries required for the service between North Sydney, Nova Scotia and Port-Aux-Basques in Newfoundland. A seasonally varying load of passengers, cars and tractor-trailers was expected, justifying a large fast vessel. Studies were made to compare costs of a one-truck-deck/one-car-deck vessel with a two truck-deck vessel, of diesel and gas turbine propulsion, and of a split-stern hull versus a conventional-stern hull. Subsequently, further studies were carried out for a vessel with a smaller load, beam and speed. The effect of these new constraints is described. Special reference is made to the need for extra care in estimates of weights, centers and damaged stability, when the constraints sail close to the margins.

This paper describes the results of studies on the wild bees of Nova Scotia, which were carried out in connection with apple pollination investigations in the Annapolis-Cornwallis Valley, Nova Scotia.The biology of the Apoidea in general is reviewed from the literature, and a list of bees taken on apple bloom is given. As the members of the genera Halictus and Andrena were found to be the most important native pollinators, the greater part of the paper is devoted to accounts of the habits and life histories of representative species.The members of the genus Andrena were found to have a simple type, such as is generally found among solitary bees. The females provision the nest and then die; the larvae develop to the pupal stage in their underground cells, then emerge as adults the following season. All Nova Scotian species studied were one-generation forms.The bees of the genus Halictus show a primitive social organization, more complex in some species than in others. The first brood consists of females only, which are apparently sterile and work at nest construction, the gathering of pollen, etc. They are followed later in the season by a brood of males and females; these females, after being fertilized, hibernate for the winter, while the males die in the fall. The hibernating habits of different species are described, and notes are given on some parasites and inquilines of the two genera.

Economic Relations

This paper contends that the legal precedents which have until so recently discouraged positive Canadian legislation, and which could still invalidate fresh legislative efforts, are based on an outdated view of the economic relations of fishermen and fish buyers. The following briefly examines the economic underpinnings of the Canadian fishermen's right to bar gain, with special reference to Nova Scotia and Atlantic Canada.

Propulsion Power

The Canadian Government, Ministry of Transport, initiated a Study of the Application of Gas Turbines to Canadian Coast Guard Vessels in 1972, which was completed in early 1974. This paper discusses the results of our findings and also new data now being used in design studies for heavy Icebreakers of Polar Class.
