579. International Trade in Maize. — The following figures, 

 statistics of the international trade in maize, including maize 

 meal, for the years 1905-9, are furnished by the United 

 States Department of Agriculture {Year Book, 19 10), and re- 

 present, substantially, the international trade of the world. 

 As there stated, " it should not be expected that the world ex- 

 port and import totals for any year will agree. Among sources 

 of disagreement are these : (1) Different periods of time 

 covered in the ' year ' of the various countries ; (2) imports 

 received in year subsequent to year of export ; (3) want of 

 uniformity in classification of goods among countries ; (4) 

 different practices and varying degrees of failure in recording 

 countries of origin and ultimate destination ; (5) different 

 practices of recording re-exported goods ; (6) opposite 

 methods of treating free ports ; (7) clerical errors, which, it 

 may be assumed, are not infrequent. 



"The exports given are domestic exports, and the im- 

 ports given are imports for consumption as far as it is feasible 

 and consistent so to express the facts. While there are some 

 inevitable omissions, on the other hand there are some dupli- 

 cations because of re-shipments that do not appear as such in 

 official reports. For the United Kingdom, import figures re- 

 fer to imports for consumption, when available, otherwise total 

 imports, less exports of ' foreign and colonial merchandise '. 



1 These results are only approximate, as the number of sacks measured was 

 small, and they therefore took up more space than they would have done if 

 stowed tightly in the ship's hold.
