The information is probably scattered through the Departments of Interior, Justice, Commerce, Labor and Navy. Either a clerk in the State Department looks up Mexican oil in a book of reference, which may or may not be accurate, or somebody's private secretary telephones somebody else's private secretary, asks for a memorandum, and in the course of time a darkey messenger arrives with an armful of unintelligible reports. The Department should be able to call on its own intelligence bureau to assemble the facts in a way suited to the diplomatic problem up for decision. And these facts the diplomatic intelligence bureau would obtain from the central clearing house. [Footnote: There has been a vast development of such services among the trade associations. The possibilities of a perverted use were revealed by the New York Building Trades investigation of 1921.]
