and the Government will be forced to plant trees in plantations 

 as has been done in Germany and France. No better use can 

 be made of Arbor Day, in the schools, than to instill the love 

 of trees in the children, and the desire to preserve what few 

 forest areas remain, within our state, intact. 



1 • Fontinalis' green tresses, the mountain streams toss. " We 

 do not need to go to the mountains to find Fontinalis. The 

 teachers in the High School can guide you to where you will 

 find it in the vicinity of the city, not many miles away from 

 Woodlawn, the city of the dead. Its long, dark-green, tresses 

 float in the cold waters of " Dog Brook " and many of them are 

 over a foot long. Its leaves are in three ranks, and boat-shaped, 

 or shell-shaped, and they have no vein. It rarely fruits, how- 

 ever, in this region, and I have only once found it fruiting in 

 the mountains of northern New Jersey. It also is common in 

 streams on the Palisades. 



"The emerald Bryum on moist shady banks unfolds its 

 rosettes." Yes, but there are ruby Bryums, silvery Bryums, 

 and golden Bryums. Bryum argenteum, the silvery Bryum, is 

 the commonest of them all, and I have seen it many a time in 

 the crevices of the side-walk on Fourth Avenue, near Fiftieth 

 Street, along the side of the walk from the Railroad in Bedford 

 Park, in the copings and stair-cases of Morningside Park, and 

 have had it sent to me from the summits of the Andes, and 

 from a door-mat in the classical town of Cambridge, Massachu- 

 setts. The tips of its leaves are without chlorophyll and end in a 

 fine bristle, and the whole plant derives its grey-green, silvery 

 tint from these characters. Its fruit is a jewel-box of the love- 

 liest description, all frosted and resplendent, with red, orange, 

 and gold, and the fringe of teeth around its mouth is a very 

 beautiful and complicated object under the microscope. Speci- 

 mens may be found in fruit in waste, sandy places, and newly 

 turned earth along the Mosholu Parkway, and duplicates will 

 be sent in quantity for the next distribution by the New York 

 Botanical Gardens, or may be had from me by sending a self- 

 addressed and stamped envelope. 



The pedicels of many of the Bryums are a bright, glossy red, 

 and the leaves in many of them, especially at the base and 

 along the vein, are also red. There are about twenty-five 

 species of the genus in the Eastern states, but only about five 

 are common in the vicinity of New York. 



"The troops of Dicranums are tilting their lances. " Those 

 lances are the capsules with their long-beaked lids and sharp-
