42 TROUT FISHING 



multitudinous brilliance. The trout 

 would bolt at sight of it. 



Still, the scientific theory about the 

 fish in relation to the winds is not 

 sufficient. It assumes that, whilst west 

 winds and south winds are always warm, 

 east winds and north winds are always 

 cold ; and the assumption cannot be 

 granted. In spring and summer the tem- 

 perature of the atmosphere is often low 

 when the wind is from the east, or from 

 the north, during a cyclone ; but during an 

 anti-cyclone it is always high. In the 

 latter case, whencesoever it comes, the air 

 is at least mild ; often, in July or in August, 

 it is positively oppressive. That is because 

 the breezes within the radius of an anti- 

 cyclone are in a sense not what they 

 seem. The wind which on the Itchen or 

 on the Test is from the north-east has 

 not necessarily come across the seas from 

 the Polar region. It may not even have 

 come so far as from London. It is a 

 north-east wind by courtesy ; but it is not 

 a true wind at all. It is only a draught.
