extreme and very unusual low temperature at Sacramento, because it 

 came direct \y off the snow and ice of the mountains, and moving so rapidly 

 that it has no time to be warmed by slowly passing over the warmer 

 region of the Sacramento and San Joaquin Valleys, but reaches us with 

 almost the same breath that it left the mountains.

THE NORTH WIND. 



The Signal Service reports show the north wind began blowing at 7 

 o'clock last night 18 miles per hour, increasing during the night to 36 

 miles, and blowing steadily from 22 to 30 miles per hour up to noon. The 

 following figures show the actual number of miles the wind traveled dur- 

 ing each hour, and the maximum or highest velocity for the same time, 

 and was: From 7 p. m. to 8 p. m., 17 miles; highest velocity, 21 miles; from 

 8 p. m. to 9 p. m., 21 miles; highest velocity, 24 miles; from 9 p. m. to 10 

 p. m., 27 miles; highest velocity, 30 miles; from 10 p. m. to 11 p. m., 27 

 miles; highest velocity, 30 miles; from 11 p. m. to 12, midnight, 28 miles; 

 highest velocity, 30 miles; from 12, midnight, to 1 a. m., 32 miles; highest 

 velocity, 36 miles; from 1 a. m. to 2 a. m., 28 miles; highest velocity, 33 

 miles; from 2 a. m. to 3 a. m., 27 miles; highest velocity, 36 miles; from 3 

 a. m. to 4 a. m., 31 miles; highest velocity, 33 miles; from 4 a. m. to 5 

 a. m., 28 miles; highest velocity, 36 miles; from 5 a. m. to 6 a. m., 30 miles; 

 highest velocity, 36 miles; from 6 a. m. to 7 a. m., 28 miles; highest veloc- 

 ity, 33 miles; from 7 a. m. to 8 a. m., 22 miles; highest velocity, 27 miles; 

 from 8 a. m. to 9 a. m., 26 miles; highest velocity, 30 miles; from 9 a. m. 

 to 10 a. m., 26 miles; highest velocity, 30 miles; from 10 a. m. to 11 a. m., 

 23 miles; highest velocity, 30 miles; from 11a. m. to 12, noon, 24 miles; 

 highest velocity, 30 miles. 



This makes a total velocity of miles from 7 o'clock last night to 12 

 (noon), to-day, 17 hours, giving an average hourly velocity of miles, and 

 a maximum, or highest velocity of 36 miles per hour between 12 (mid- 

 night), and 1 a. m.; 2 and 3 a. m.; 4 and 5 a. m., and 5 and 6 a. m. 



ICE IN THE RIVER. 



_ Captain Foster, of the Steamboat Company, says this is the first time 



since 1854 that he has noticed ice floating down the Sacramento River. It 



has been floating down this morning, measuring about one sixteenth of an 



inch in thickness, and no doubt, these thin spiculse of ice formed along
