" On the Isthmus there are but two seasons, winter and sum- 
mer. In winter the north wind materially diminishes the inter- 
tropical heat on the southern coast. The average temperature 
in October and March, at six o'clock in the morning, is 74° 
Fahrenheit, and at twelve, in the shade, 81°, and has never 
fallen lower than 78°. The average temperature is 75° between 
eight P. M. and two A. M., and 71° from three to five in the 
morning. 
" The influence of the rainy season also tends to lessen the 
great heat of the summer. The temperature during the hottest 
part of the day when it rains does not exceed 81°. At eight 
o'clock in the morning it maintains itself at 75°, and at three 
o'clock in the morning it seldom falls as low as 73°. Usually 
the nights are of almost uniform temperature. 
" In summer ,when the sky is clear and the sun shines with all 
its brightness, the thermometer varies between 87° and 90° from 
eleven in the morning to four in the afternoon. At eight o'clock 
in the evening it falls to 79°, and at four in the morning to 75°, 
" The month of November is the coldest month of the year, 
and those of May and Jane the warmest. Towards the close of 
April, the thermometer, at twelve, in the shade, occasionally 
ascends to 90°, and rarely descends to 85°. The forepart of the 
night on such occasions maintained itself at 79°, and in the 
second part the temperature descended to 74°. 
"In November the thermometer never falls below 70° from 
nine to five o'clock in the day; at eight in the evening it has 
never stood at less than 59°, nor less than 55° from four to six 
in the morning." 
Mr. Trastour, having been engaged upwards of a year on the 
Isthmus, has collected much valuable information, which could 
not be prepared in time for this report. He is now employed 
in drawing up a large map of his survey of the southern division, 
embracing sixty miles of the Pacific coast. 
As Mr. Trastour has made full and complete surveys of the 
harbors on the Pacific, I have only deemed it important to make 
the following extracts from Mr. Temple's Keport, as to embody 
the whole would have been but a repetition of Mr. Trastour's 
results. Mr. Temple says :
