counting both banks. The charge is 10s. per day per rod. The five 

 lowest beats are fished from 15th January. The furthest up beat is 

 not fished till March. One rod goes with each beat, and spinning 

 baits are largely used till about April, when the fly seems to come 

 into greater favour. Mr. Stewart, the hotelkeeper, has kindly given 

 me the catches for the last four years.

Mr. Geen had 7 fish one day here at the opening of season 1909. 



Visitors fishing from the Kenmore Hotel are charged 10s. per fish 

 caught. 



In referring to the upper tributaries of the Tay, the Tummel and 

 Garry and the Lyon, mention has at the same time been made of 

 the times at which fish may be first expected in each, and it may be 

 noticed that these times are different. The Lyon has fish as early 

 as Loch Tay, the Tummel receives fish rather later, and the Garry is 

 the latest of the three. Some three years ago I was able to compare 

 thermometric readings from each river, when it became evident that 

 in early spring the Lyon had a temperature practically equal to that 

 of the Tay as it comes from the loch, the Tummel was slightly 

 colder, and the Garry was colder still; in other words, the order 

 in which fish enter these tributaries corresponded with the times 

 at which the temperature of each approached that of the main 

 river. 



No doubt the Lyon varies considerably in temperature from year 

 to year, according as the snow lies in the early spring months. If 

 January and February pass without much severe weather, any differ- 

 ence of temperature between the Lyon and the Upper Tay is 

 insignificant, so that, except for the greater volume of water in the 

 main river, there is practically as much inducement for fish to 

 ascend the Lyon as the Tay. Further also, it is found that in extra 

 warm springs fish not only enter the mouth of the Tummel early but 

 ascend that river, and that they are also found up in the Garry at an 

 earlier date than usual. 



Subjoined is a chart of curves which shows means of actual 

 readings in the Tay at Grandtully (above the Tummel Junction), 

 the Tay at Perth (after receiving the cold Almond), the Lyon, 

 and the Garry. It will be at once noticed that the Garry curve 

 is constantly lower than the Tay and the Lyon. In January the
