ment that the differences between our northern and southern 
Nations are a constant feature of our district, at all events dW 
the months in which we have experimented, and also that they are 
evidenced even by a short haul of the trawl. On September 4th, 
a northern and a southern station, viz., Skate Roads and Druri^e 
Bay were visited and the results offer a striking contrast. Another 
point of general interest is illustrated by the figures for Skate Roads 
on September 27th. It will be seen that the numbers of plaice 
were practically the same per hour's trawling during a period o 
five successive hours, when three hauls were made. I el 
clearly be said that such a general dispersion of the dom an 
popula ion over the ground was due to tide, and it T ite 
probable that the dense fog prevailing before and during the Xle 
time of the experiment was the cause. The figures serve to show 
moreover, that a further series of similar hauls will be n eC et y
