104 ANNUAL REPORT 



responding to the combined influence of the afternoon sun and the 

 presence of the low barometer, which you have already learned 

 invariably brings higher temperature, has arisen to 60° and 

 even 70°. The orange orchardists of Florida were yet uncon- 

 scious, unless warned through the signal service, of their im- 

 pending doom. 



At 11 P. M. of the 7th we find the low area covering the mouth ol 

 the Mississippi, and that the zero line has spread eastward to Fort 

 Smith, Arkansas, from which j)oint it extends due northward to 

 St. Paul and the St. Louis river, where it turns eastward through 

 Lake Superior into Ontario. The temperature has fallen in 

 Texas to 30° at Indianola and Galveston, but is still 60° in 

 Florida. 



The chart for the morning of the 8th presents the low centre 

 at Montgomery, Alabama, and the zero line extending from the 

 Eio Grande below El Paso, Texas, by way of Palestine, Little 

 Eock, Keokuk and Lake Superior. Temperature of Florida 

 from 50° to 70°, while all of Texas is below 20°. 



Eight hours later (the heat of the day) the low is in eastern 

 Georgia, while zero has extended westward to the Mississippi 

 river, but is receding in western Texas. The orange orchards 

 are still unharmed in Florida, but are suffering in Louisiana. 

 At 11 P. M. the low has reached the mouth of Chesapeake bay, 

 and the zero line now takes in Memphis and northern Missis- 

 sippi. The Gulf coast from Pensacola westward has a tempera- 

 ture of 20° and lower, but east and south Florida are above 50°. 



The morning chart of the ninth shows the low area on the 

 New Jersey coast, and zero extending from Santa Fe via Deni- 

 son, Vicksburg, Chattanooga and thence northward to Cincin- 

 nati, Chicago and Lake Superior. Jacksonville and Cedar Keys 

 have a temperature of 30° while Sanford and Punta Rassa have 

 40° and 50° respectively. At this observation we note the 

 greatest thermometrical gradient that occurred during the 

 storm, the readings being, at the centre of the low, in ^N'ew 

 Jersey, 28.8 inches, while on the northern border of your state 

 it was 30.8 inches, The disparity of readings were unusual, 

 which gave the storm its peculiar force. 



The 3 p. m. chart shows the low on the coast of New 

 Hampshire, with the zero line comparatively unchanged. The 

 night observation of the ninth shows the low area in Central 

 Maine with zero extending still more to the eastward. The 

 temperature is rising rapidly in Texas and the southwest, but
