 of those years figures were incomplete, and so estimates for previous years have been 

 substituted.

Nearly 90 per cent, of the world's potato-crop is grown in Europe and only 

 about 11 per cent, on the American Continent. The probable reasons for this large 

 difference are because, in Europe, labour is more plentiful and cheaper, and also 

 potato-growing is carried on more extensively among the poorer classes.

In the same period, 1911-15, the average production in millions of bushels is 

 given in Table III. for the chief potato-producing countries, together with their 

 average yield per acre for the years 1900-15, inclusive. 



TaUe III. 



From Table III. it will be noted that Germany and European Russia together 

 produce over 2,900,000,000 bushels, or over 50 per cent, of the world's potato-crop. 

 The greatest average yield per acre is obtained by Great Britain and Ireland and 

 the lowest by the United States.
