niorate the association of this Academy of Sciences with the 

 first exploration of these remains. Alessrs. Daggett and Fisher 

 ])erfected the mechanical arrangements and produced a gavel, 

 the head composed of a vertebra of the Giant Sloth and the 

 handle of the wood of the AIcNab Cypress found upright as it 

 grew when the Sloth and Sabre-tooth Tiger fought each other 

 under its branches. The parts are as perfect and sound as 

 when entombed more than two hundred thousand years ago. 

 A half-tone representation of this unique souvenir will "be 

 found herein. 



Dr. Davidson expressed the hope that succeeding Chair- 

 men may find in this unique Gavel a continued stimulus for 

 further scientific research and investigation.

 officers of this Academy, a list is appended of those who have
