1868.] HOOKER — ON FORESTRY. 455 



2. A collection, in the shape of books, of the indigenous 

 and naturalized woods. Each species is represented by 

 several specimens, differing in their origin and qualities. The 

 specimens, of which there are 1,300, are divided into two classes ; 

 namely, woods of ordinary leaf-bearing trees, and of conifers ; 

 these in each class are arranged alphabetically. 



3. Collection of truncheons of the most important indigen- 

 ous species ; 223 specimens. 



4. Experiments and observations on the density of woods, 

 particularly with regard to age. Specimens exemplifying the 

 opinions given. 



5. Collection of seeds and fruit of indigenous and naturalized 

 species. 



6. Complete collection of corks of all ages and qualities, and of 

 French production, furnished by the cork oak (Quercus mber) 

 and the western oak (Q. occidental is). 



7. Barks and astringent substance suitable for tanning or 

 dyeing. 



8. Resins from the Pinus maritima and P. Laricio ; methods 

 of procuring them, and their various products. 



9. Charcoals. 



10. Different products resulting from the carbonization of 

 wood. 



11. Forest sawmills ; three models. 



12. Instruments for felling, prunning, etc., trees, and for 

 collecting resin. A pusher for directing the fall of trees felled by 

 uprooting. The 'Flanmi' saw Rollers for the removal of 

 logs from young plantations without injury to the latter. 



13. Relievo of the valleys of Barr and Andlau (Lower Rhine), 

 to show the arrangement of the forest roads established there. 

 Sledge tracks with sledges, tramway with waggons, metalled 

 roads. 



14. Relievo of the perimeter of the plantations of Labouret, 

 above Digne (Basses Alpes). Photographs of mountains to 

 be laid down with grass or replanted. 



15. Photographic forest herbarium, consisting of photographs of 

 the branches with leaves, fruit, and flowers of the various 

 forest trees, all of the natural size. 



It only remains to add that the specimens are well selected and 

 excellent, the method of ticketing leaves very little to be desired, 

 and the arrangement is admirable.
