THE SUITABILITY OF AMERICAN WOODS FOR PAPER PULP 63 
cells of which are very little longer than their diameter. A few special uses 
might be developed for this material, but it could hardly be used for standard 
pulp products on account of the probable cost of collection, nonuniformity of the 
pulp obtained, low yields, and the difficulty in completely removing soil and 
other foreign matter from the material before cooking. 
Mechanical Pulp 
Not determined. 
Cabbage Palmetto (Sabal palmetto) 
Other names in use. — Palmetto and cabbage tree. 
Range. — Coast region from North Carolina to southern Florida, and on the 
Gulf coast to western Florida. 
Oven-dry weight per cubic foot, green volume. — 23 pounds. 
Fiber length. — 
Sulphite Pulp 
Cabbage palmetto under the sulphite process yields 35 to 40 per cent of dark, 
raw, and brash pulp not suited for any of the common uses. 
Sulphate Pulp 
Cabbage palmetto can be reduced by the sulphate process under low steam 
pressure to satisfactory pulp fairly easy to bleach. The pulp is stronger than 
aspen soda pulp, and may be used in the manufacture of book, magazine, and 
other similar papers, preferably in combination with 20 to 40 per cent of bleached 
pulp from coniferous woods. The pulp consists of a mixture of fairly long 
fibers and pithy material. The proportion of pithy material, however, does not 
seriously affect the character of the sheet except in so far as ij: makes it weaker 
than would be the case with the long-fibered portion alone. Yields of 40 to 45 
per cent are obtained, requiring 25 to 30 per cent of standard bleaching powder. 
Soda Pulp 
Cabbage palmetto when cooked by the soda process yields 35 per cent of 
coarse, tender fiber difficult to bleach and not suited for any of the common uses. 
Mechanical Pulp 
Not determined. 
Cane (Arundinaria macrosperma) 
Other names in use. — Large cane and giant cane. 
Range. — River bottoms from Virginia to Florida, westward to Louisiana and 
along the Mississippi and its tributaries as far north as Kentucky, Tennessee, 
and Missouri. 
Oven-dry weight per cubic foot, green volume (in piles). — 10 pounds. 22

Sulphite Pulp

Soda Pulp 
Cane reduces readily by the soda process to an easily bleached pulp having 
greater average fiber length than aspen soda pulp and capable of use in the manu- 
facture of book, magazine, and similar papers. It could probably be used without 
admixture of longer-fibered pulps from coniferous woods. The fiber is soft, 
opaque, and contains much less pith than is usual for this sort of material. 
Yields of 33 to 42 per cent are obtained, requiring 15 to 18 per cent of standard 
bleaching powder. 
Mechanical Pulp 
Not determined. 
22 When chopped for the digester, the material occupies 1 cubic foot for each 14 pounds of oven-dry ma- 
terial, in comparison with 10 pounds to the cubic foot of space occupied by spruce chips.)
