108 MAINE AGRICULTURAL EXPERIMENT STATION. 19OI. 



Dr. Chestnut sent us specimens of the "Valley White Acorn." 

 Quercus lobata, "one of the acorns which is most abundantly 

 used by the Indians of Mendecino county, California." This is 

 analyzed as number 6312. In shelling the nuts it was fOund 

 that about half of them were spoiled. The edible portion of 

 good ones made up the sample taken for analysis, but the propor- 

 tion of shell (refuse) to kernel (edible portion) is based upon 

 all of the acorns, good and poor. 



Weight of acorns, 130 grams. 



P^dible portion, kernels, 93 grams, 71.54 per cent. 



Refuse, shells, 37 grams, 28.46 per cent. 

 The composition is given below together with that of the 

 acoxns previously analyzed: It will be noted that the acorns of 

 Quercus lobata are much lower in fat content and higher in car- 

 bohydrates than the other samples examined. This affects the 

 fuel value markedly, as the fats have much greater heats of 

 combustion than the carbohvdrates.
