'06 



This was an exceedingly wet month the amount of rain being 

 upward of 4^ inches. There were only 4 days on which rain 

 did not fall. The barometer was remarkably low on the 6th, 

 7th and 24th; and its average height was lower than in any 

 month during the preceding 15 years at least. On the 1 8th 

 the tide at Chiswick rose higher than it has done since the 28th 

 December, 1821. The mean temperature was about a degree 

 below the average. Frost at night occurred only twice ; that 

 on the 21st was such as to destroy the Dahlia flowers. The 

 ground was so deluged as to be rendered totally unfit for being 

 properly worked ; and for most garden operations the weather 

 was very unfavourable.
