photographs in various positions. When not in use these apertures 

 were closed by cloth doors which were provided with hooks and 

 eyes such as are used by dressmakers, but of extra large size. 

 An opening about five inches square in the top served quite suc- 

 cessfully for ventilation. 



Such a tent can be set up on rocky places where stakes cannot be 

 used; and there are no guy lines to obstruct the camera field. It is 

 possible to see more or less of what is going on outside of the tent 

 through the cloth itself, although holes of small size give a clearer 

 view. When dark clothing is worn, one's movements inside are 

 not noticed. 



The lower margin of each side and end of the tent was held down 

 by a pole which ran through a hem in the cloth, and the ends of the 

 poles were anchored with weights when a wind was blowing. Thus 

 in Plate IV, Fig. 1, pieces of wood appear at the corners, for this 

 purpose. A brisk breeze was blowing when the picture was taken 

 as may be seen in the bellying of the side of the tent. 



This tent with considerable additional anchorage in the form of 

 rocks went through an unusually violent storm without injury or 

 displacement. Only a small portion of the heavy fall of rain came 

 through the cloth. It was found wise to carry permanent tent 

 poles carefully fitted to the corner blocks, in a bundle as a part of 

 my outfit. Drift boards were used as a floor. 



The chief objection to this form of tent is that it is not high 

 enough to permit the observer to stand upright. During a long 

 day, I could not avoid becoming much cramped even when I tried 

 shifts from a sitting to a reclining position and so on. I have since 

 used a tent of similar form but larger and over six feet tall. The 

 poles are all of bamboo and the corner fittings are of brass. The 

 number of openings has been reduced but they have been placed 

 in carefully selected positions. The sides and ends are all sewed 

 together except at one corner where the entrance is placed. Tapes 

 are provided for closing the entrance. This tent is much neater 

 and far more comfortable, and it can be set up with the adjustments 

 of equipment in less than fifteen minutes. 



I found it necessary, as has been the experience of others, to have 

 a companion leave the tent after having been inside with me. He 

 would also leave the island with our boat, and he would not return
