this evil, one side of the paper must be gently clipped again in the 

 water, only touching the disarranged ramuli, and so on all round the 

 plant, until properly adjusted. After thus far progress has been 

 made, pieces of common muslin should be laid gently over the 

 plant, to absorb the moisture and coloring matter which might 

 escape; then placed in a book or under other slight pressure until 

 nearly or quite dry. Then withdraw your muslin, and place the 

 plants under considerable pressure. This done, your specimens are 

 ready for your cabinet or your album. The time required for this 

 operation is but little, as practice will give speed and suggest facili- 

 ties. Never foiget to write date and location upon your specimen, 

 as it may save you future difficulty in your study. 



The form and structure of Algae are very vaiied, — some being so 

 simple and minute as to be composed of one cell or sac, sufficient 

 to contain the germ for propagation. Others, as the Macrocystis 

 luxurians, are so extensive and compoundly ramified, as to cover a 

 vast area in circumference, and to exceed the highest forest tiee in 

 altitude. Captain Marryatt, in his Naval Officer, page 153, says — 



11 There is a remarkable peculiarity on the Island of Tristan 

 D'Acunha. Its shores, to a very considerable extent out to sea, 

 are surrounded with the plant called Fucvs Maximus, mentioned by 

 Capt. Cook ; it grows to the depth of 60 fathoms, and reaches in 

 one long stem to the surface, when it continues to run along to the 

 enormous length of three or four hundred feet, with alternate 

 branches at every foot of its length. 



" Thus, in the stormy ocean, grows a plant higher and of greater 

 length than any vegetable production on the surface of the earth, 

 not excepting the Bannian tree, which, as its branches touch the 

 earth, takes fresh root, and may be said to form a separate tree. 



" These marine plants resist the most powerful atiacks of the 

 mightiest elements combined ; — the winds and the waves in vain 

 combine their forces against them : uniting their foliage on the 

 bosom of the waters, they laugh at the hurricane and defy its 

 power. The leaves are alternate, and when the wind ruffles the 

 water, they flap over one against the other, wiih a mournful sound. 



" The branches or tendrils of these plants are so strong and 

 buoyant, that when several of them happen to unite, a boat cannot 

 pass through them. I tried with my feet what pressure they would 

 bear, and I was convinced that, Willi a pair of snow shoes, a man 

 might walk over them.*'
