So that according to the above table there is an average difference of 

 tv/enty-two days between the flowering of the same plants in the earliest 

 and latest of the above districts. 



Then, as showing the difference made in the dates of flowering by an 

 early and a late season, I may instance the average date of the black- 

 thorn in the central or midland district of England, which in 1894 was 

 March 27, and in 1895 April 27, while the hawthorn was first in blossom 

 in 1893 on April 27, and in 1891 it did not flower till May 28, giving a 

 range for each of these two shrubs of thirty-one days. 



Table B gives the mean dates of first flowering of the thirteen 

 plants and their variations from the average during the past fifteen 

 years in all those districts where the Society has had throughout the 

 whole period a sufficient number of observers. It will be seen that 

 the most forward season was that of 1893, and the most backward that 

 of 1891, while last year the dates were as nearly as possible average. It 

 says much for the accuracy of the observers, and for the soundness of 

 the system adopted, when we see year after year throughout this table 

 such consistency in the results obtained. 



Mean Results, with their Variations from the Fifteen Years' Average 

 (1891-1905), for the Thirteen Plants in those Districts where there 

 have been sufficient Observations to warrant Comparisons being 

 made.
