STATISTICAL TABLES. 



I. Epitomised Tables of the Gatch landed at Aberdeen, in 1913, by 

 British and Foreign Steam Trawlers. 



J^lfote. — The figures here given are not identical with the official 

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

 Annual Eeport for 1913, pp. 72, 73. The greater part of the 

 Scottish landings by foreign 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 Report 

 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 

 Report ; 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 speak- 

 ing, these statistics are based on a unit of measurement, viz. the 

 so-called hundredweight box, and not upon a unit of weight. 



In the total quantities dealt with, the discrepancy between 

 these figures and those of the official returns amounts, after 

 taking the foreign landings into account, to about 2 3 per cent. 

 After further taking account of the differences of estimated 

 weight, the discrepancy practically disappears.
