Callithamnion, etc. The Cyclopedia Britannica mentions 

 the fact that it is distributed in beds through the North 

 Sea and British Channel, fifteen to twenty miles long, 

 and yet not more than 600 feet wide. It is common 

 along all our shores, from New York northward. It 

 grows, of course, in deep water. Its fronds reach 

 up, at least, to the surface. The old fronds should 

 be allowed to dry off a little before mounting, but 

 the young ones, covered with hairs, may be floated 

 out in water. The long plants are best disposed of 

 by coiling up neatly on the sheet of mounting paper, 

 and drying in the usual way, under pressure. They 

 seem to adhere well.

 abundance along our whole coast. It may be known 

 by its very dark brown or quite black color, both 

 in the water and on paper; and by its long, slender, 

 naked, mostly undivided branches, which sweep off 

 from all sides, and, in not ungraceful curves, over-
