ON THE EARTHQUAKE AND VOLCANIC PHENOMENA OF JAPAN. 129 



plete arrangement would be to have two lines of piping, placed at right- 

 angles. The cost of the installation would be about 5001. 



In conclusion to this Report it must not be overlooked that the re- 

 marks on the Great Earthquake only aim at giving an outline of phe- 

 nomena which have been observed, and the general character of the 

 results to which they lead. More detailed accounts will not be ready 

 for publication for some months. 



Nineteenth Report of the Committee, consisting of Professor Everett, 

 Professor Lord Kelvin, Mr. Gr. J. Symons, Sir A. G-eikie, Mr. J. 

 G-LAiSHER, Mr. W. Pengelly, Professor Edward Hull, Professor 

 Prestwich, Dr. C. Le Neve Foster, Professor A. S. HERSCHELy 

 Professor Gr. A. Lebour, Mr. A. B. Wynne, Mr. W. Galloway,. 

 Mr. G. F. Deacon, Mr. E. Wethered, and Mr. A. Strahax, 

 appointed for the purpose of investigating the Rate of Increase 

 of Underground Temperature downivards in various Localities 

 of Dry Land and under Water. {Drawn up by Professor 

 Everett, Secretary.) 



Regret has been expressed in previous Reports at the scarcity of observa- 

 tions from America. An important contribution towards supplying this 

 lack is described in the ' American Journal of Science and Art ' for 

 March, 1892, under the heading ' Preliminary Report of Observations 

 at the Deep Well, Wheeling, West Virginia, by William Hallock.' A coiay 

 of this Preliminary Report was sent by Mr. Hallock to the Secretary, 

 and further details have been elicited by correspondence. The passages 

 between inverted commas in the following account are in Mr. Hallock's 

 own words. 



The well belongs to the Wheeling Development Company. ' It was 

 commenced in September, 1890, and sunk with rapidity to about 4,100 ft. 

 by April, 1891. Then the Company, despairing of getting oil or gas, 

 were about to abandon it, when Professor I. C. White persuaded them 

 to deepen it and give it to science. Drilling was recommenced, and early 

 in May they stopped at a depth of 4,500 ft., fearing to go further with the- 

 old Manilla rope.' 



' The hole was sunk by the ordinary oil-well outfit, i.e., a jumper drill 

 on a rope.' It is dry, with the exception of a few feet of water at the 

 bottom. 



' About ten days after drilling stopped, Mr. F. H. Newell ' and Mr. 

 Hallock ' took a series of temperatures at every 250 ft.' 



' The thermometers, immersed in zinc buckets of water, 3 ft. high and 

 4 inches in diameter' (^ inch less than the diameter of the bore), 'were 

 left in place for twenty-four hours. This series of May does not differ 

 essentially from the later ones of June and July, and shows no sign of 

 heat due to jumper.' 



' In June ' Mr. Hallock ' returned to Wheeling, and during June and 

 July made two very careful and complete series, which are given in the 

 table. Each series touched evei-y 250 ft. ; but the two series were shifted 



1892. K
