" Owing to the resilient nature 

 of the ground, it was found 

 advisable not to allow anyone to 

 move about, and shutters were 

 fitted to the 16-foot and De la 

 Rue coronagraphs, which could 

 be worked from the dark-slide 

 ends. Winkelmann, who has two 

 instruments in his charge, has only 

 a step or two to make, and it is 

 impossible to prevent him moving. 

 In the following programme for 

 the eclipse, the times mentioned are 

 standard time (ten hours east), as 

 given by Dr. A. M. W. Downing, 

 F.R.S., and also local time at 

 Pyramid Rock in the entrance to 

 Port Davev, which is long. 145° ^5' 

 E. and I'at. 43° 22' S. As the 

 position of the observatory is long. 

 146° E. and lat. 43° 20' S., the 

 eclipse will start a little later, and 

 finish a trifle earlier. The time was 

 again checked on May 6 by Messrs. 

 Brooks and Young, and ^he chrono- 

 meter error found." 



(Here follows a large table 

 showing the exposures to be 

 made in the various instruments,

" Port Davcy, May q, 1910. 



" Rain cominenced on the afternoon of May 8, and 



continued steadily all through May 9. No drills 



were possible. On the night of May 8 the dark 



slides were filled, and all were taken up to the ob- 



NO. 2126, VOL. 84] 



servatory on the Monday afternoon, and, in spite of 

 the rain, the instruments were made ready; but 

 exposures were limited to one slide, which was opened 

 at 5 seconds and closed at 200. There was a 

 tremendous downpour during the eclipse, but it 

 cleared a little afterwards. During 

 totality there was a stretch of 

 bright sky on the western horizon, 

 and soon after sunset the clouds 

 dispersed and a bright, starry night 

 followed. 

 __ " Immediately after eclipse the 



barricades were pulled down and 

 the ground prepared for the final 

 packing." 



Since the receipt of the above 

 communications both Mr. McClean 

 and Mr. Young have arrived home. 

 They have both suffered from the 

 (fleets of the hard work and in- 

 clement weather, and the former is 

 still in the doctor's hands. While 

 Mr. McClean has had considerable 

 experience in roughing it, he de- 

 scribes his recent work in Tas- 

 mania as the most trying that he 

 has yet had to contend with. Never- 

 theless, his keenness for eclipse 

 work is by no means damped, for 

 he is now looking forward to the 

 eclipse of next year, which will be 

 visible from islands in the Pacific 

 Ocean, and is already commencing 

 arrangements to observe it.

WE regret to have to record the death, at the early 

 age of forty-one, of Mr. J. B. Carruthers, 

 assistant director of agriculture in Trinidad. Mr.

J. Brook 



Carruthers only took up his new appointment last 

 aututnn, and with characteristic enthusiasm entered 

 at once verv cnergeticallv upon the task of making 

 himself familiar with his fresh surroundings. The 

 possibilities of rubber cultivation was the principal 

 subject to occupy his attention, and to this end he 

 visited most of the chief estates in Trinidad. Thence
