studied in 1874 by Johnstrup himself with the assistance of 

 Dr. Steenstrup. In the same year the latter geologist also 

 made a preliminary reconnaisance of the third of the "great" 

 mineral localities of Greenland, viz. Kangerdluarsuk at Juliane- 

 haab, and in 1876 he continued his studies here. 



Since 1876 the scientific expeditions to Greenland made at 

 the expenses of the Danish state followed in rapid succession, 

 as from that year at least one exploring expedition is annually 

 sent out to Greenland. In 1877 the chief management was 

 intrusted to the "Commission for the Direction of the Geological 

 and Geographical Exploration of Greenland" (for which commis- 

 sion Johnstrup was the chairman until his death in 1894), and 

 from that time not only mineralogicai and geological expeditions 

 were sent out, but also, and in large numbers, expeditions the 

 chief purposes of which fell under other sciences. Among these 

 latter expeditions the charting-expeditions have had a special 

 importance for the procuring of the large material from which 

 this hand-book has been prepared. 



The charting expeditions to the west-coast of Greenland 

 were, with very few exceptions, arranged in such a way, that 

 a young student with mineralogicai knowledge joined them as 

 an assistant. As these expeditions — of which 15 were sent 

 out in the years 1877—1897 — worked up a detailed map of 

 the whole western coast from Cape Farewell to 74V2 N. Lat., 

 a mineralogical reconnaissance was at the same time obtained, 

 even if it were only a cursory one, of wide regions which had 

 never before been visited by mineralogists. 



Of expeditions with principally mineralogical (or geological) 

 purposes five have been sent to West-Greenland since 1876. 

 These expeditions, the work of which was restricted to rather 

 narrowly bounded districts, carried home exceedingly rich 

 mineralogical results. They will be mentioned here in chrono- 

 logical order. The first was Dr. Steenstrüp's journey to the 

 district of Juliiinehaab in 1888: this expedition made a rich
