According to Dr. Nansen's theory the vessel will get frozen in somewhere in the neighbourh o o d of the Liakoo Islands, and be conveyed by the presumed movement of the ice to and past the North Pole, and be finally dis. charged by this supposed current into the East Greenland seas. The crew will consist, all told, of net more than twelve men, and provisions for five years will be carried. The Boyle Automatic System of venSlation has been adopted, and is applied as shown
This arrangement has been designed by Dr. Nansen and Mr. l~obert Boyle to meet the special requirements of the case, and will be employed when the vessel is frozen into the floe ice, which will be for the greater part of each year. Both the upcas t and downcast ventilators are absolutely weatherproof, and though always in action no water can pass down them into the saloon, into which the cabins are also ventilated. Adjustable hoods are provided to protect the ventilators from snow.
