LETTER OF TRANSMITTAL.

U. S. DEPARTMENT OF AGRICULTURE, BUREAU OF CHEMISTRY, Washington, D. C., October 31, 1907. SIR: I have the honor to submit for your inspection and approval a manuscript containing the results of investigations made in the sugar and microchemical laboratories of this Bureau upon the analysis and composition of American honeys and the microscopic examination of the same. Dr. E. F. Phillips, in charge of apiculture in the Bureau of Entomology, rendered most valuable assistance in procuring samples of pure honey for investigation and offered many practical sugestions from the bee keeper's point of view. The samples of Hawaiian honeys examined were furnished by Mr. D. L. Van Dine, entomologist of the Hawaiian Agricultural Experiment Station, who also supplied information upon the complex conditions which affect the composition of Hawaiian honeys.

I recommend that this report be published as Bulletin No. 110 of the Bureau of Chemistry.

Respectfully,

Hon. JAMES WILSON,

Secretary of Agriculture.

H. W. WILEY,
Chief of Bureau.
