Concerning the early work in China, M. Schulz has found something interesting:
"Working through the Pastor Russell Lecture Bureau, something called The Bible Study Club was organized and a paper entitled Bible Study was published"
From "The Chinese Recorder", August 1913 he has quoted:
"The Continent, a Presbyterian journal noted for opposing Russell and The Watch Tower sent someone to visit the Bible Study Club offices located in the Metropolitan Building in New York City. The magazine reported:
The office to which Mr. Noble invited correspondents to write is occupied by a business concern of an entirely different character, which reports that “Mr. Noble” simply receives mail at that address. This firm disclaims all connection with him. On a corner of the glass in the door is the revealing line, “Pastor Russell Lecture Bureau.”"
