THE CAMP AT JEUR. 53 



instruments of observation, which made indeed a brave show. 

 Some of these only just arrived in time from England. 



The Ja[anese contented themselves with less in the way of 

 apparatus. A long bellows camera working off the coelostat, 

 which was of a different pattern from Professor Naegamvala's, 

 and apparently more complicated, had its other end fixed 

 against the window of a little portable dark-room which the 

 party had brought with them from Japan ; and the exposures 

 were made with a sliding shutter. With this they obtained 

 a disc about 4 in. in diameter. A short focus telescopic camera 

 in addition, moved by clockwork, gave them another set of 

 photographs of the corona on a smaller scale. They did no 

 spectrum work. All their arrangements and observations were 

 carried out by themselves. They had little outside assistance 

 >ave for common coolie work. They brought their own 

 carpenters with them. 



Professor Burckhalter, in his little nook among the trees by 

 the side of an old garden well, just outside the town of Vangi, 

 011 the north, was simpler still in his apparatus. He intended 

 doing little, but doing that well ; and, judging from his results, 

 he was in this eminently successful. His only instrument was 

 the Pearson telescope, which he duplicated by having a second 

 lens of the same make and power, mounted in a home-made 

 tube, clamped on to the top of it, the two working together. 

 These gave him images about 2 in. in diameter. By a very 

 ingenious device of his own he was able to control the exposures 

 of one set of his plates, so as to give the outer streamers a long 

 exposure and the chromosphere a shorter one upon the same 

 plate. This was done by a revolving disc in front of the plate, 

 with a slit cut out of it wide at the circumference and less at 

 the centre. The disc was revolved by clockwork at the back of 

 the plate, the attachment passing through a hole made in the 

 plate itself. This hole falling in the centre of the moon's disc- 

 did not matter much, but its effect upon a print would be 

 uncommonly like some newly disclosed cavern or empty crater 

 upon the moon. 



Professor Naegamvala, who had by far the greatest number of 

 a i -rants upon the ground, was helped by the Principal, some 

 of the professors of the College, and other gentlemen, and a 

 >trong contingent of native students whom he succeeded in 

 knocking into shape by constant drills for a week in advance. 

 Helpers for Professors Campbell and Burckhalter arrived on the 

 ground only a day or two before the event, and were recruited 

 from the British Naval and Military Departments at Bombay. 

 The Jaj>anese depended entirely upon themselves, and they were 

 an ample party for the few instruments they were using. 



The day of the eclipse wore on, anxious hands adjusted and 

 readjusted the instruments, the drilling of the assistants was
