THE POWAN, POLLAN, VENDACE, AND GRAYLING 285 
and some thirty-five to forty years ago this was rather a big 
annual event. 
‘« As for the present status of the vendace, I hear from time 
to time of small takes by net (the Lochmaben magistrates, I 
believe, give the requisite permission ) of a dozen or maybe two. 
It has always been a very unusual thing to take more than a 
very few dozens, big and wee fish, all told. I have no reason 
to believe that this most interesting species is less numerous, 
or perhaps I should say more scarce, than ever it was.” 
That vendace in Lochmaben should be few in number is 
no wonder ; the marvel is that they should have maintained 
their existence in small shallow pools swarming with pike. 
They cannot be very numerous in the English Lake District, 
for Mr. John Watson, in all his long experience, has only 
seen half a dozen specimens in all. They never take fly or 
bait, and can only be caught in nets. 
Genus THYMALLUS 
The genus Thymallus is very closely akin to that of 
Coregonus, and was treated as one therewith by Artedi and 
Lacepede; but modern ichthyologists have separated it, chiefly 
on account of the long, many-rayed dorsal fin. It consists 
of five species, whereof only one is British.

In the grayling we come back to the true game fish, for 
he is only second to the brown trout in the esteem of fair 
anglers. Nevertheless, it happens sometimes that this choice
