xiv INTRODUCTION. 



of the laws which regulate the atmosphere, and a careful investi- 

 gation of all its phenomena. 



XLY. Another heautiful feature in this system is, that it costs 

 nothing additional. The instruments that these observations call 

 for are such as are already in use on hoard of every well-condi- 

 tioned ship, and the observations that are required are precisely 

 those which are necessary for her safe and proper navigation. 



XLYI. As great as is the value attached to what has been ac- 

 complished by these researches in the way of shortening passages 

 and lessening the dangers of the sea, a good of higher value is, in 

 the opinion of many seamen, yet to come out of the moral, the 

 educational, influence which they are calculated to exert upon the 

 seafaring community of the world. A very clever English ship- 

 master, speaking recently of the advantages of educational influ- 

 ences among those who intend to follow the sea, remarks : 



" To the cultivated lad there is a new world spread out when 

 he enters on his first voyage. As his education has fitted, so will 

 he perceive, year by year, that his profession makes him acquaint- 

 ed with things new and instructive. His intelligence will enable 

 him to appreciate the contrasts of each country in its general aspect, 

 manners, and productions, and in modes of navigation, adapted to 

 the character of coast, climate, and rivers. He will dwell wdth in- 

 terest on the phases of the ocean, the storm, the calm, and the 

 breeze, and will look for traces of the laws which regulate them. 

 All this will induce a serious earnestness in his work, and teach 

 him to view lightly those irksome and often offensive duties inci- 

 dent to the beginner."* Sentiments which can not fail to meet 

 with a hearty response from all good men, whether ashore or afloat. 



XLVn. Never before has such a corps of observers been enlist- 

 ed in the cause of any department of physical science as is that 

 which is now about to be eno^as^ed in advancino^ our knowledsje of 

 the physical geography of the sea, and never before have men felt 

 such an interest with regard to this knowledge.
