of Gatun Lake, had to be enlarged. The new center dock, which has 
concrete piers, should be adequate for many years to come. The old 
shingle roof of the Fuertes House, at end of the Pearson trail, was 
replaced with one of galvanized corrugated iron.

URGENT NEEDS 
First on the list of urgent needs is a more adequate supply of elec- 
tricity on a 24-hour daily basis. The present small generators are 
inadequate, and the equipment is in need of repair. An addition is 
needed for the kitchen to make room for electric refrigerators. To 
reduce fire risk, the present kitchen and the proposed addition should 
be remade of concrete blocks and tile. Also on the urgent list is a 
larger building of concrete blocks to take care of the expanding library 
and herbarium, as well as the species index and scientific equipment, 
all of which must be in a fireproof building with provision for heaters 
to reduce the humidity.
