F. S. Dodge — Kilauea in August, 1892. 245 



approximations, and show careful work, but the later instru- 

 mental survey shows that lie overestimated the diameter of the 

 lake by about 100 feet. His diameter of Halema'uma'u, 

 2,400 feet, agrees very nearly with mine, as given in the table 

 at the end of this article. 



As shown on Bishop's map of April, and my later one, the 

 location of Halema/uma'u is almost identical with that of 1386, 

 and the new lake is exactly over the mouth of the great fun- 

 nel-shaped depression shown by Mr. J. S. Emerson in April, 

 '86, but eastward of the Dana Lake of 1888. The area of 

 Halema'uma'u is not much less than in '86, being about 100 acres 

 as compared with 153 acres by Mr. Emerson's survey. 



Of the general condition of Kilauea little may be said, as 

 the changes are hardly noticeable. With the building up of 

 the Halma'uma'u cone, in the period from 1888 to March, 1891, 

 the summit was changed from Central Rock, with an elevation 

 of —321 to a point directly north of the great pit, with an 

 elevation of —262, a rise of 59 feet. The whole region to the 

 east and south, by the same agency was raised until it exceeds 

 Central Rock in height by about 40 feet, and on the west side 

 about 30 feet, making the conical form of Halema'uma'u more 

 noticeable. 



The trail over the old floor of Kilauea has been improved 

 somewhat and marked by stone monuments at frequent in- 

 tervals, throughout its length, and there is a trail entirely 

 around Halema'uma'u, and another leading to some interest- 

 ing caves southwest of the pit. 



The new Yolcano House is a vast improvement over the 

 old one, and should be well patronized by tourists and others, 

 as it is exceedingly well conducted, and all necessary comforts 

 are provided by the present management. 



With the completion of the new Government road from 

 Hilo, the Yolcano of Kilauea should have a much larger num- 

 ber of visitors than ever before. 



In making my recent survey, valuable assistance was ren-~ 

 dered by Mr. W. E. Wall, of the Government Survey, and 

 also by the managers and guides at the Yolcano House.
