CLIMATE.

The smaller relative hiiniidit}^ also contributes toward making the 

 summer climate an agreeable one. Springs with a mean annual 

 temperature of 45^ or 50^ F. are not infrequent at high elevations in 

 the Djurdjura range. 



Table l.—i]fean temperatures (in degrees Fahrenheit) of localities in the coast region 

 of Algeria, as compared with the California coast. 



A comparison of the temperatures of localities in Algeria and in 

 California, as given in Table 1, is instructive. Of the Algerian 

 stations, Oran and Algiers are situated on the seaboard, the tirst in 

 western, the second in central Algeria. Data from these localities 

 should be representative of conditions along the coast, except in the 

 extreme eastern part of the colony. With them are to be compared 

 San Francisco, San Luis Obispo, and Los Angeles, representing the 

 coast of California. Orleansville is the metropolis of the great valle}^ 

 or rather plain, of the Chelitf, the most important of the large inland 

 valleys of the coast region in Algeria. Setif, as has already been 

 remarked, lies south of the mountain chain that bounds the coast 

 region, and has an elevation of over 8,000 feet. Topographically, 

 and in some of its climatic peculiarities, it belongs rather to the high 

 plateau than to the coast region, although agriculturally it is more 

 nearly related to the latter. Fresno and Sacramento are representa- 

 tive points in the two great interior valleys of California — the San 

 Joaquin and the Sacramento. They should afford an interesting com- 

 parison, especially with Orleansville. Fort National, at an elevation 

 of over 3.000 feet, in the heart of the most mountainous region of 

 Algeria, is to be compared with Colfax, in the foothills of the Sierra 

 Nevada, north of the center of California. 



Oran has the same mean yearly temperature as Los Angeles, but 

 has higher mean temperatures for the summer and lower for the win- 

 ter months, so that Los Angeles has the more equable climate. At 

 Algiers the yearly mean temperature is not very different from that 

 at Oran, but the mean temperatures for the winter months are gen- 

 (>rally higher. San Francisco and San Luis Obispo fall considerably
