will be seen that very often there are long groups of •+■ or — quan- 
1 tities, and that frequently several of the numbers are very large to 
which these signs are attached; and it is the accumulation of these 
| departures, more than in isolated cases, which requires the attention 
of the horticulturist. These periods are variable in length, frequently 
of a week’s duration, and less frequently of a fortnight; taking the 
! latter as a limit, the following numbers show all the periods of excess 
of 14 days’ or more than 14 days’ continuance. 
By taking the periods of excess above the average in each month, 
in which the number of days extend to 14 or more, and entering 
1 them opposite the month in which the period commences, we have the 
following:—
