RED AND WHITE FIR. 



XYLOMETER CORDWOOD TEST. 

 By R. W. Taylor, Forest Assistant. 



The test was carried on in the wooclyard of the Crown Colum- 

 bia Paper Company at Floriston, California, the immediate ob- 

 ject of which was to ascertain as accurately as possible the ex- 

 act cubic contents of an average cord of Red Fir cordwood such 

 as is used in making paper pulp. The ultimate object was to ap- 

 ply the factor thus obtained to a Red Fir content volume table 

 so that estimates made in reconnaissance work in the Red Fir 

 region could be readily and accurately converted into cord meas- 

 ure. 



The Xylometer used was a galvanized iron tank 2.465 ft. in 

 diameter and approximately 4I ft. high, graduated on the inside 

 in i/ioo of a foot. Each stick of cordwood was immersed 

 separately and its volume recorded. The cords were piled after 

 the sticks had been immersed, making each one as far as it is 

 possible to do so, of the standard dimension 4'x4'x8'. 



The wood measured was a mixture of red and white fir cut 

 from the Crown Columbia Paper Company's holdings near Flori- 

 ston, California, averaging 35% Red Fir (Abies nwgnifica) and 

 67% White Fir (Abies concolor). As far as can be ascertained, 

 both by inspection and measurements, there is no difference 

 in the form of the red and white fir cordwood. This is borne 

 out by the figures in the table, which show that the cubic con- 

 tents of the various cords bear no relation to the percentage of 

 the two species. jNIoreover, the average number of sticks per 

 cord of the 25 cords is 60. A stack of cordwood containing 

 10.87 cords and 91% red fir and 9% White Fir measured in 

 another part of the yard averaged 58 sticks to the cord. Thus 

 it will be seen that the size and form of the sticks of the two 

 species are practically the same. 



The accompanying tables show the result of the test and the 

 resultant factor applied to the volume table.
