CLIMACIUM AMERICANUM IN DECORATION. 
A. Bruce Jackson. 
Until recently I was unaware that Climacium Americanum had any 
decorative value. It is, however, frequently used by English florists for 
wreaths and crosses, the dendroid stems being tied in bunches with a pleasing 
effect. The much to be regretted practice of dyeing, which is as usual 
resorted to, will not however commen . itself to a bryologist. A Newbury 
florist tells me that Climacium comes to him from the Oriental dealers in a 
dried condition and is called “ Resurrection Moss,” a name given I suppose 
because it has the property with other mosses of expanding when moistened. 
Two bunches of the moss colored, one olive-green and the other a hideous 
dark red, are before me as I write. A friend sent me two or three .years 
ago specimens of species obtained from the same shop, and on one of these 
there are two capsules, a somewhat rare condition. As five shillings is 
charged for a cross made up solely of this moss, its commercial value must 
be considerable. I am indebted to Mr. H. N. Dixon for the identification.

WEBERA SESSILIS AND ANTS. 
Charles C. Plitt. 
A year ago, I learned that ants were very fond of the spores of Weber a 
sessilis (Schmid.) Lindb. Finding a pretty specimen of this interesting little 
moss, I brought it home. Not being able to put specimen away as soon as I 
reached home, it was left over night in the vasculum ; in fact, it was several 
days, before I again got the time to examine the specimen. What was my 
surprise to find it over-run with ants ! Examining the specimen 1 found that 
a piece had been gnawed out of the side of nearly every one of the capsules 
and that the spores had been removed. Every body familiar with this moss, 
with its large capsules, readily sees what an especially fine inducement it 
offers for such a depredation. 
This at once raised the question, whether such depredations ever occur 
in a state of nature. I was almost convinced that such do occur, but it was 
only recently that I found further proof that they actually do occur. On one 
of my trips during the early part of the present month (Oct. 1906), I came 
upon a pretty little patch of the Webera. Taking up a small portion of 
it, I saw that it was immediately over an ant’s nest, I at once examined the 
capsules and found them gnawed, just as I found that the ants last year had 
gnawed the capsules of the plants left in the vasculum. 
That this moss is thus pilfered at times, seems pretty evident. It would
