DIRECTIONS FOR COLLECTING^ ETC. 335 



basket lined with oil-skin^ or a bag- of that or any 

 other water-proof material. Many red sea-weeds 

 require the greatest care, and must be laid out as 

 soon as possible ; first ascertaining, by the aid of a 

 pocket lens or a microscope (if the plant be minute 

 in its proportions), whether it be in fruit, and if so, 

 of which description, spores or tetraspores. The 



Book^ will probably prove acceptable to the reader. " The 

 Brag consists of a series of barbed hooks attached to a trans- 

 verse bar, and connected with a rope. It ought to weigh at 

 least five or six pounds. This is to be dragged along among 

 the leaves of the large sea-weeds, care being taken when the 

 ground is very foul not to allow it to fall into holes among 

 the rocks, in which it would be liable tp be caught. By suf- 

 fering it to drag among the sea-weeds, soriie of these will be 

 detached, and being caught by the hooks will readily be 

 hauled up ; and such leaves often afford a rich harvest The 

 Naturalist's Dredge is an iron rectangular frame, made with 

 a scraper at each side, and having a bag attached to it in the 

 usual manner. Its handles are moveable, being connected 

 by eyelet-holes with the bars of the frame below, and 

 united where they join above, by a ring and screw, which 

 when wished can be unscrewed, and the whole falls into 

 a small space. The great value of this dredge is that 

 it cannot be overset, each side being the same, and this, 

 when dredging in deep water, is a quality of the greatest 

 value."
