H1B TIME 8 saysEverything, small or great, that concerns trade ot traders, comes alike within its scope. There is hardly one of its chapters that might not be expanded into a volume, so compressed, so wide sought, and so miscellaneous is the varied information which it ocrveys. Its statistical tables and its extracts from consular reports abound in interesting facts. It tells us something of the contents of a dosen recent Blue Books, each of them as bulky as itself. Nothing, indeed, comes amiss to it which by any possibility or stretch of language can be in- •'Ivded under its comprehensive title?* THE MORNING POST says:—“It is, as its many readers are aware, a record of the recent movements and present position of British and Foreign Trade, compiled from reliable sources, and is a very valuable, if not indispensable, publication to Merchants and others engaged in commerce.” All Applications for the Insertion of Advertisements in this Journal must be addressed— '‘The Board of Trade Journal*’ (Advertisement Department), 3, Wellington St., Strand, London.
