METEOROLOGY. 



The sides of the table are placed^parallel to the cardinal points of 

 the compass, and these are also marked on the edges of the paper, so 

 that at a glance at any subsequent time the direction from which the 

 wind came at a particular date can be determined. The date of each 

 paper is written at the top, and the hour scale calculated for every 

 day. The sheets are of good printing paper, of about two feet in 

 diameter, and are bound^in volumes for^ready reference. 



This apparatus has been in operation for nearly three years and has 



given entire satisfaction.
