THE SMALL GAMl:: OF THE SEA I'JT 



in February and March. x\nother showed the number of 

 mackerel caught by three particular steam drifters working ofi 

 Cornwall in May. The average number of hours of sunshine 

 for the seven years was 217*5. The average number of mackerel 

 caught was 435,000. In every case where the sunshine was less 

 or more than the average, the catch of mackerel followed suit, 

 and the curves of sunshine and the mackerel curve follow each 

 other most faithfully. The figure is reproduced here by per- 

 mission of Dr. x\llen (Fig. 26).

Science w^ould not, probably, be prepared on these data to 

 say that the correlation bctw^een February sunshine and May 

 mackerel w^as estabhshed. But it is fairly certain that no 

 drifter owner would fail to see that the inquiry has a very direct 

 bearing on his work. Suppose that a drifter owner had suc- 

 ceeded in preventing Dr. Allen from continuing his experiments 

 with diatoms in 1898. In that case would the ' practical ' 

 results have been attempted or achieved by 1908 ? It is 

 unnecessary to enlarge. It may be that by 1908 every drifter 

 owner in Yarmouth and Lowestoft was aware of what Dr. Allen
