and, when allowed to fall in its place, keeps the contents of the 

 case clean. The other advantages pertaining to the automatic 

 spring letter-case are that the ]>apers are not perforated or other- 

 wise injured; they are kept flat, there is nothing to get out of 

 order, and a pile of jmpers two inches thick cr.n be readily inserted, 

 and abstracted without nece3sarily upsetting the others.

No matter who moves first, the 

 game ought to be drawn. But, 

 ;is will be seen, care and judg- 

 ment are required to maintain the 

 opposition. 



1. K to B2 

 If White plays 1. K to B3 he 

 must lose, as Black will reply 

 with K to B4, gaining the opposi- 

 tion, and next move White must 

 lo,=e a Pawn. If Black had the 

 first move, and would play K to B 1 

 he would be similarly positioned, 

 and lose the opposition by White 

 playing 2. K to B3, K to Kt4.

An interesting lectnre on Greenland was given in the RoyaE 

 Victoria Hall, Waterloo. bridge-road, on Tuesday, April 21, by 

 Dr. P. H. Carpenter, of Eton. He first described, with the help of 

 lantern illustrations, the situation and general .appearance of the 

 country, which has an area of 800,000 square miles, but is 

 inhabited only on the west coast, the east coast being so blocked 

 with ice that ships can reach it only in a mild summer, while 

 travelling in the interior is only possible with dog-sledges. The 

 lecturer described the huge glaciers or streams of ice which, formed 

 by the compression of the snow on the mountains, descend through 

 the valleys to the sea. Sometimes huge masses break off from 

 them and form icebergs, one of which was stranded in Baffin's Bay, 

 in water half-a-mile deep, and was calculated to contain 1,000' 

 million cubic yards of ice. Many of the fjords are filled with bergs 

 thus formed, which are very dangerous to ships.
