STATISTICAL TABLES. 



L Epitomised Tables of the Catch landed at Aberdeen, in 1914-1916, 

 by British and Foreign Steam Trawlers. 



Note. — The figures here given are not identical with the official 

 returns for the Port of Aberdeen, set forth in the Board's 

 Annual Keports for the years in question. The latter include 

 under the head of Aberdeen only landings by British vessels, 

 but the greater part of the Scottish landings by loreign vessels 

 (pp. 122, 123) also refer to the Port of Aberdeen, and these 

 foreign landings are here included. Secondly, as has been 

 explained in our Fifth Eeport on North Sea Investigations 

 (1913, p. 207) the method of estimating the weight of certain 

 fish has, since 1909, been altered, in the direction of greater 

 accuracy, in the Official Eeport ; but here, for the sake of 

 uniformity and comparison, the method in use in earlier years 

 is still retained. It must be carefully understood that the 

 weights given in these Tables are based on estimate and not on 

 actual weighings. Strictly speaking, these statistics are based 

 on a unit of measurement, viz. the so-called hundredweight box, 

 ' and not upon a unit of weight. 



The total discrepancy between the two series of tables, after 

 making allowances for the above differences of treatment, is 

 very small, and even insignificant.
