The climate at Napa (figs. A-E, — ) is less varied with respect 
to temperature range than at either Ithaca or Waco, but the rainfall 
occurs during a much more limited period. None of the winter 
temperatures is low enough to restrict the spawning operations of 
amphibians. Conceivably, the animals could therefore breed at any 
season were moisture conditions suitable. But the rainfall is con- 
centrated in the period from October or November until April; 
from May until September rain falls, on the average, on not more 
than three days per month and in total amount of one inch or less. 
The annual cycle shows low temperature amplitude, the midsummer 
temperatures approaching those of Ithaca, but there is a dry season 
not found at either Ithaca or Waco.
