Case 2. — This case displays the Russian method of collecting 
the oils and resins of the European Pitch Pine {Pinus sylvestris). 
The Russian method is to strip off the bark from a large por- 
tion of the circumference of the tree and scrape off the exuda- 
tion. This is continued for a period of five years. Note the 
original package of pitch scrapings as sold in the native markets; 
the resin, colophony and “pek,” as well as the various products 
of tapping and of distillation exhibited on the top shelf of the 
case. 
Case 3. — Note the various products of turpentine orchard- 
ing from Pinus palustris in Georgia, as shown in tubes on the 
bottom shelf of the top of this case; also Mexican “resina” 
from Pinus Montezumae, Japanese “Chan” from Pinus densi- 
flora, “Khasia” from Pinus khasya of British India, turpentine 
from the Indian Pinus excelsa, and “trementina” from the 
Mexican Pinus teocote. Amber, a fossilized resin from prehis- 
toric pines, from the newly discovered beds on Staten Island, 
New York, is also exhibited in this case. Note also particu- 
larly fine natural amber nodules and a clear cut piece showing 
the inclusion of a Caddis Fly, from Germany. 
Case 4. — This case contains a complete series of trunks of 
the Georgia Pine {Pinus palustris) showing the method of 
“boxing” for turpentine and the appearance of the trees in the 
orchard from the first year’s boxing to the fifth year’s burning- 
off. 
Case 5. — 'Base of a Cluster Pine {Pinus pinaster) showing 
the Portugese method of boxing the trunks and collecting the 
resin. 
Case 6. — Illustration of the conversion of Spruce pulp from 
Pice a mariana into fiber ware. Note the pulp boards and the 
examples of the processes necessary to render the pulp imper- 
vious. 
Case 7. — -Top. Exemplification of the conversion of Black 
Spruce {Picea mariana) into the common newspaper stock of 
to-day. Note the yellow appearance exposure to light gives 
paper. Compare with this the Swedish product from the Nor- 
way Spruce {Picea excelsa). Below this observe the various 
Japanese utilizations of thin shavings of Hiba {Thujopsis dola- 
brata) and the chip work and twine made from this species. 
Case 8. — Note the paper pulp trees of Japan: Momi {Abies 
flrma), Tohi {Picea Alcockiana) and Tsuga {Tsuga Sieboldii).
