illustrating the label. They are in a glass-covered box and can easily 
be referred to ‘at home’ with no danger of breakage in passing around.

The collection of fifty specimens was delivered to the club and is 
in the custody of the Historian, where it may be studied by anyone 
interested. The collection is a very valuable addition to the club prop- 
erties and it is hoped will form a nucleus for a permanent exhibit of 
scientific interest. 
Rainiera stricta, a plant belonging to the composite family, was 
found on the 1912 outing growing in abundance all the way from the 
Manastash ridge to the slopes of Mt. Rainier. This plant bearing the 
name of the great mountain had previously been reported only from 
the mountain itself or the region directly south. 
Mr. E. B. Webster, editor of the Olympic Leader, who was a 
member of the Mountaineers’ first annual outing, has the honor of 
adding one to the list cf plants known to grow in the state of Wash- 
ington. The new plant belongs to the composite family and has been 
named Senecio Websteri by Mr. C. V. Piper, government agrostologist 
and author of “The flora of Washington.” WINONA BAILEY.

Lake Sammamish is situated several miles east of Seattle. The 
submerged forest in this lake has an area of about fifty acres and it is 
near the west side, not far from the head of the lake. The broken-off 
tops of the trees are awash at summer level of the lake. This fall the 
lake has been lower than ever, the tops being about four feet out of 
water. Most of the trees stand nearly vertical, a few are considerably 
inclined. The size of trunks at water surface ranges from about eight 
inches to three and a half feet in diameter. The trees are of the usual 
forest variety of this region. 
Forty-eight years ago, Mr. C. B. Bagley of Seattle first saw these 
trees while on a canoe trip. He found it troublesome to paddle 
through them. At that time the broken tops extended high above the 
water for varying lengths. His impression was that they then had been 
submerged perhaps forty or fifty years. 
Apparently this phenomenon is not the result of a slide from any 
adjacent high steep ground. The nearest shore land is rather flat and 
gently sloping for a good distance from the lake. It is possible, how- 
ever, that a precipitous side of a deep channel gave way, causing a 
slide. A sudden damming of the lake is improbable, as the formation 
at outlet does not indicate it, nor do the shores of the rest of the lake. 
A subsidence of the ground seems to be a probable cause, but what 
caused the subsidence is not apparent. R. H. McKEE.
