on the general principles which were followed. In designing the house the severe 

 climate of South Georgia, characterized by a heavy snowfall in winter and violent winds 

 at all times of the year, was taken into special consideration. The building consists of 

 a stout wooden framework bolted on to a concrete foundation, and the walls were con- 

 structed with the special object of insulating the house against cold. On the outside 

 of the wooden framework there are two layers of boarding, enclosing a layer of felt 

 and a layer of waterproof paper, and on the inside another layer of boarding and 

 a layer of compressed cork finished with asbestos sheeting (poilite). The interior 

 partitions consist simply of the wooden framework covered with poilite. The roof is 

 of galvanized iron, with a layer of boarding and insulating material beneath, and all the 

 windows are double, having an outer iron and an inner wooden framework. These 

 arrangements serve admirably to insulate the walls. Brickwork was used for the 

 chimneys and walls of the boiler house, coal cellar, etc., and for part of the outside 

 store shed. 



The arrangement of the rooms is shown on the accompanying plan (Fig. 35). The 

 house is so placed that the windows of the laboratory face the beach, and the con- 

 servatory and windows of the living rooms, while having a restricted view, are on the 

 sunny side of the house.
