On the Sun Column as seen at Sandwich Manse, Orkney y 

 in April 1852. By C. Clouston. 



The perpendicular column of light which appeared repeatedly at 

 sunset and sunrise during April, deserves a more particular account 

 than the usual monthly report contains, as this is the most northern 

 locality in which I have yet heard of its appearance. 



When seen in the evening, it was generally immediately after the 

 sun had sunk either below the horizon, or behind a bank of clouds 

 there. 



It was rather wider than the apparent diameter of the sun, and 

 extended upwards for about 15°, widening a little towards the top, 

 and becoming fainter, so that there was no defined boundary ; but it 

 was sometimes much shorter, and could be distinctly seen, when it 

 was less than the semidiameter of the sun above the horizon, either 

 when vanishing by descending, as it generally did, or as it last appeared 

 on the 3rd of May, without rising more than about 1°. 



Though at first it seemed to be a law that it must descend as the 

 sun descended below the horizon, yet on one occasion, at least (on 

 the 26th), it vanished by ascending, or the base disappeared first. 



It was generally remarkably perpendicular, but sometimes had a 

 perceptible inclination to one side, and followed the course of the suu 

 northwards.
