From this table it appears that the amount of rain is about 

 one-half as gieat^in San Francisco as in any of the American 

 states east of the Mississippi. Here, all the rain falls in the 

 winter and spring; there, the amounts are nearly the same in 

 the four seasons. They have as much rain in their summer 

 and autumn as we in our winter and spring. We have less 

 rain than Liverpool and Rome, and about the same amount 

 with Paris. San Diego has only one-half and Fort Yuma one- 

 seventh the rain-fall of San Francisco, which latter place is 

 surpassed nearly seventy-five per cent, by Humboldt Bay. At 

 Fort Yuma, and all through the Colorado Desert, the rain 

 comes not in the rainy season of California, but chiefly in the 

 summer and fall, synchronous with the wet season of North- 

 western Mexico. Unfortunately, we have no statistics of the 

 rain-fall in the Sierra Nevada, or in the Great Basin, within 

 the limits of this state. 



The least rain in San Francisco, during any rainy season 

 since 1852, has been 19 inches; the largest amount, 24 inches. 

 I obtain the following figures from statistics kept in this city 

 by Mr. Thomas Teimant, from 1850 to the present time: 



The average rain-fall m January is 3.52 inches. The most 

 notable departures from that average were in 1858, when there
