Xll PREFACE. 



with his own hand, and to colour, or super- 

 intend the colouring of each particular 

 impression. 



He therefore presumes to hope that he 

 has succeeded in giving a useful collection 

 of the leading flies for every month in the 

 season, and that any one, who may be led 

 by it to a choice of flies from the stock of 

 the manufacturer, or to the construction 

 of his own, will not have cause to repent 

 of having consulted the catalogue, chiefly 

 composing the fourth Chapter. 



But since in his endeavours to improve 

 the art of fly-making, careful observations 

 were made relative to some of the habits 

 of the Trout and Grayling, and of many 

 insects upon which these fish prey ; it is 

 hoped that a few of these observations, inter- 

 mixed with a little useful information, and 

 some remarks on other points more or less 

 connected with the principal sul)ject, will not 

 be thought inappropriate. These form the 

 subjects of the three preceding Chapters.
