 nature by Mr. Sutton Davies, was of a somewhat 

 different character, being closed in at the top. It 

 was firmly fixed up in a fir tree, about eighteen feet 

 above the ground, and some twenty feet distant 

 from the first rapid of the Adolfstroom. 



This box was 36 inches long, and the entrance 

 was very large, the whole structure being secured 

 to the tree by a branch passing through a hole at 

 the back, the top of the box being lightly nailed on. 

 The box contained moss, dead juniper twigs, birch 

 twigs, and a very little down. 



A fourth box was of the same size as No. 2, and 

 placed about ten feet from the water, with the 

 entrance hole facing inland; it was secured in 

 position upon the tree by the stump of a branch 

 passing through a hole at the back of the box ; 

 the bottom of the box was formed of bark, secured 

 by strips of wood nailed across.
