Mr. Mason to Mr. Uhl.

No. 312.]

Sir: Referring to your special instructions, No. 153, of the 3d instant, requiring the return of samples of such evaporated American apples as may have been condemned by the police authorities of Frankfort or its district for alleged contamination with salts of zinc, I have the honor to submit, with the two samples of such apples that are herewith returned, a report describing in some measure the history and general nature of the regulations and law under which such merchandise is inspected in Germany.

The circular of the Imperial Government on this subject is translated and embodied in the text of the report. The other inclosures are presumably of interest only to the Department of Agriculture.

I am, etc.,

Frank H. Mason,
