INTRODUCTORY CHAPTER. Iv 



Gregory's, Hold-fast Tom, Prosperous Bay, and on the windward 

 coast of the island, considerable quantities of it might be collected 

 very readily and at a trifling expense. 



No. 2. is a lichen which grows upon the gum-wood trees all 

 over the island, but particularly on those in the Honourable 

 Company's plantation at Long Wood, where it is abundant. 

 From this lichen, it is presumed, a beautiful colour may be ex- 

 tracted ; it might also be found valuable as a substitute for gum, 

 if used according to the process in Lord Dundonald's patent. 

 That nobleman's report states " that lib. of dry (prepared) lichen 

 " will do as much work in calico printing as l^^lb. of gum 

 " Senegal, and the difference of price makes a saving of c£45. on 

 " each table or press, in war time, and half that in peace." The 

 lichens his Lordship specifies are " those which grow on trees 

 " and shrubs." It may not be held unreasonable to suppose that 

 the lichen of this number may possess superior mucilaginous 

 qualities, growing on the bark of a tree which itself yields a very 

 pure and excellent gum. 



No. 3. is another lichen, found as No. 2. 



No. 4. a whitish crustaceous lichen ; found in abundance all 

 over the island. 



No. 5. is a box containing a specimen of a yellow lichen : this 

 is found in many parts of the island, both in the interior and 

 towards the sea ; it grows on trees, rocks, and arid soils ; it is 

 not so plentiful as the other kinds. 



No. 6. is a lichen growing on rocks, intermixed with No. 1. and 

 is in great plenty. 



No. 7. a small fibrous lichen ; found generally, and in abun- 

 dance on rocks, walls, &c. 



There is no doubt but this island produces other, and perhaps 

 infinitely more valuable lichens than any of those collected ; spe- 

 cimens of which with all care shall be made.
