But before dismissing the subject, let us compare some 

 actual growth and weather figures, taking the best growths 

 for each month with corresponding weather, and taking, 

 also, the worst growths for each month, with the month's 

 weather, evergreens and deciduous trees separate as usual, 

 as in Tables V. and VI. 



In Table V. (evergreens, 12th May 1888), the poor rain- 

 fall (3"11 inches) is supplemented by 4*56 inches, which 

 fell in thirty hours from 2nd to 9th April, three days 

 before the measuring day. 



12th November 1888. — The 2-76 inches of rainfall is 

 supplemented by 26 6 inches, which fell in twelve and 

 a half hours from 3rd to 7th October, five days before 

 the measuring day. 



12th July 1889. — The poor rainfall of 1'95 inch is 

 supplemented by 3-22 inches, which fell in thirty six and 

 a half hours from 2nd to 10th June, two days before the 

 measuring day. 



In the same Table (deciduous trees), 12th November 

 1888 has been commented upon in "evergreens." 



12th December 1888. — The pretty good rainfall of 

 4'62 inches is helped by a fall of 1"21 inch during seven 

 days from 1st to 11th November; and the evergreen 

 good growth this month is also no doubt helped by the 

 same cause. 



As to deciduous trees in the sleeping season, it does not 

 appear that any useful purpose could be served by a 

 detailed examination of these figures, for, as previously 

 remarked, shrinkage takes place in these mouths, and this 

 cannot be considered simply as if it were intensified bad 

 growth. It may be sufficient to notice that the best 

 growths in sleeping season are accompanied by a total of 

 32"12 inches, and that the worst growths in this season 

 are accompanied by a total of 2 3 8 inches, and that the 

 average annual rainfall for these seven years is 44*05 

 inches. 



In Table VI. (evergreens, 12th November 1891), out of 

 the 5*1 9 inches of rain, 361 inches fell in fifteen and a half 

 hours between 1st and 9th November; and the measuring 

 day being 12 th November, it is probable that the full 

 effect of this rain had not yet made itself felt.
