Condensed instmictions for fal'ing and recording observations. — 

 On the inside of the front cover of tJie observation form, 1210 A, there 

 are condensed instructions for recording weather observations. The 

 experienced marine meteorological observer will find these condensed 

 instructions adequate for entering daily weather reports on the 

 forms. Parts III, IV, and Y of this manual are designed to fur- 

 nish information in detail regarding the most modern and desirable 

 methods of taking weather observations on shipboard. The instruc- 

 tions and explanations therein are based upon the specifications laid 

 down by the International Meteorological Organization and should 

 eventually become universal. The general use of the International 

 Code in ships' weather reports sent by radio makes it necessary that 

 tlie international methods of recording observations be followed. 



When questions arise in connection with any phases of the ob- 

 servational work, the observer should consult the appropriate sec- 

 tions of parts III, IV or V; however, the experienced observer, as 

 well as i\\^, beginner, should read through them carefully at his lei- 

 sure in order that he mav be familiar with their contents.
