Notes. 



The observations at Port Alice were made by Mr. Fred Pordage, at Lubwa's by Mr. W. H. Wilson, and. 

 at Port Victoria bv Mr. C. W. Fowler. For the position of these stations see tlie Sixth Report, for 

 1897. 



All observations are referred to the mean lake-level at each station for the year 1896. 



On comparing the Results for 1897 with those for 1896 it will be found that during the last decade of 

 July the lake-level was 3^27 in. higher than during the corresponding decade of 1896, and this notwith- 

 standing that on January 1, 1897, the level of the lake »tood 3-6 in. below the Datum level, whilst on 

 January 1, 1896, it stood 7^8 in. above it. This difference in level is due to the heavier rainfall of 1897. 



The lake was lowest in the beginning of the year, highest in June. The extreme range during the 

 seven months for which records are available amounted to 8 in. at Port Alice, to 9^7 in. at Lubwa's, and 

 to 7'6 in. at Port Victoria. 



For remarks on the conditions governing the rise and fall of lake, see last year's Report. \ 



Correction : In column 5 of last year's table. Instead of 15-40 ri'iid 1-54. ■ 



That is, difference between the lowest and highest level during each month.
