 For the information of messengers and others who aspire to appointment as 

 observers in the Weather Bureau, it is stated that hereafter the civil-service 

 observer examination will be made to include the first four studies indicated in 

 these instructions. 



In conducting the examinations required by Instructions No. 79, 1899, the super- 

 vising examiner in Washington will prepare all iiuestions and forward the same to 

 the official designated to hold the examination, which shall take place under .such 

 directions as to details as the supervising examiner may prescribe. 



An observer must have passed in all studies prescibed for grades below and 

 including his own before he can be examined for promotion to a hierher grade. In 

 case of failure to pass in any subject, he may be again examined in sucli subject 

 after the lapse of three months. 



Thus far 75 candidates have been examined, of which number 58 

 have passed satisfactorily in three or more subjects. 



The advancement of an employee from the lower to the higher 

 grades does not depend wholly upon his ability to pass a creditable 

 examination in the required subjects. In addition, he must show, in 

 the performance of the duties to whicli he may be assigned, that he 

 possesses the qualifications necessary' to properly conduct a station, 

 or pei'form work equivalent thereto, under all conditions that may 

 arise.
