Buist makes the following statement: " Believing 

 that your readers would like to know the dates 

 and the number of smoults marked as they left 

 the pond, I append the necessary particulars. 

 The numbers marked were about one in every 

 100 that left, so that about 120,000 departed, 

 and more than double their number remained.
