c^i." During totality, there remained visible to the n. e. only a luminous 

 point, not much larger than the planet Mars and of the same color. 

 With a small telescope the whole disk of the moon was visible. 



c = 2.3 Gray, Eldridge, Cal., (276). I repaired hastily to my telescope house. 

 On the walk thither the eclipse was so thorough that it cost me some 

 trouble to locate the moon, and many on night duty were unable to 

 see the eclipse because of want of knowledge where to look for the 



moon. I saw the eclipse well Used binoculars, finder and 



telescope. All the instruments revealed the dull, coppery hue of the 

 expanse of the moon's disk. [Apertures not stated.] 

 Pargoire, Vinhlong, Indo-China, (279) ; weather and means not 

 stated. Nearly total when the moon cleared the horizon haze. 



d = 2.5 The eclipsed part was totally invisible. Later it began to reappear at 

 its eastern limb. 



Flint, Madison, Wis., (275) ; the sky seemed remarkably clear, down 

 to the horizon all around ; astronomical twilight. 



br=6.3 Opera-glasses; it was an exceedingly dark eclipse. It is difificult for 

 me to believe that any but a remarkably dark eclipsed moon could 

 have disappeared entirely in the degree of dawn indicated 



■ • Barnard, Mt. Hamilton, (274) ; I think it probable that this was a 



dark eclipse. 



Newton, Irvine's Landing, B. C, (278) ; a dark eclipse. 



igiS IX 4; 1.435 ; Grade 



c Near both poles ; near Manzanillo and near C. Comorin. 



Kuyper, Medan, Sumatra, (280) ; sky very pure. 

 c =r 2.8 Means not stated. During totality the shadow appeared of a bluish 



gray. Later it remained of a reddish brown, very dark. 



Schafer, Port Byron, Ills., (281); sky not stated. Civil twilight, 

 a = 7.0 6 inch ; the shadow was very black, and not a trace could be seen of 



that portion which it then covered. 



1914 III 11; 0.916; Grade 2 



c Antarctica, S. Pacific. 



Nolte, Newton, Mass., (284) ; very favorable weather conditions. 



c^ 1.3 At the moment of greatest eclipse, it was light enough to render the 

 chief surface details visible in a field-glass. 

 Schafer, Port Byron, Ills., (285) ; the evening was an ideal one. 

 6 inch ; when the shadow had advanced as far as ... . Mare Sereni- 

 tatis, .... I could see some of the larger markings, such as Gri- 

 maldi, the dark area in Riccioli, the Sinus Iridum, Aristarchus, Coper- 

 nicus, Plato and Pico. 



c := 1.5 At the middle of the eclipse .... with a pair of 8-power field-glasses, 

 the maria were plainly visible. 

 Cordier, Menton, (282) ; sky not stated. 



b = i.9 With n. e., noted the redness of the disk, and the visibility of the 

 plains and the seas. 

 Tramblay, Montpellier, France, (286) ; exceptional sky.
