EXPLORATIONS AND RESEARCHES. 



The " increase of knowledge " is one of the fundamental objects of 

 the Smithsonian Institution, and toward the accomplishment of that 

 object it has inaugurated and maintained or has participated in 

 astronomical, anthropological, biological, and geological explora- 

 tions in every portion of the world, resulting in greatly increasing 

 our knowledge of the meteorology, the geography, the fauna and 

 flora, and the ethnologj^ of all lands, and in the acquisition of a large 

 amount of valuable material for the National Museum. The Insti- 

 tution has likewise, through special grants, aided laboratory re- 

 searches in practically every line of natural science. The extent of 

 these explorations and researches during the last 60 years covers a 

 wide range, although a great deal more of most important work 

 could have been accomplished had adequate funds been available. 

 Friends of the Institution have many times, and particularly during 

 the last few years, generously aided the work through the contribu- 

 tion of funds for specific purposes, but much yet remains undone, 

 and opportunities for undertaking important lines of investigation 

 are constantly being lost through lack of means to carry them into 

 execution. 



I will here allude only briefly to some of the activities of the Insti- 

 tution in these directions during the year and for details of other 

 investigations may refer to the appendices containing the reports 

 of those directly in charge of the several branches of the Institution.
