Halloween or Hallowe'en or All Hallows Eve

HAPPY HALLOWEEN !! 

Halloween
or
All Hallows Eve

Halloween falls on October 31, which in the old Celtic calendar was the last day of the year, its night being the time when all the witches and warlocks were abroad.  On the introduction of Christianity it was taken over as the eve (even or e'en) of All Hallows or All Saints.

 Of course, most young people know that the most important part is "trick or treating" - and the treats are the most important part of all!!

Changing Leaves !

As the days get shorter and frost starts to appear in the morning, those deciduous trees start preparing for winter - giving us some brilliant colour !

What causes this change ?
Without sufficient light and water, photosynthesis shuts down, and trees must live off food stored during the growing season.

As photosynthesis ceases, the leaves lose their chlorophyll, which gives therm their green colour.  Without chlorophyll, other colours emerge - yellows, oranges, and reds.
In sugar Maples, the red happens because glucose remains.
The yellows and oranges are normally in the leaves but the chlorophyll overshadows them until photosynthesis stops.

At any rate the poetry of colour is beautiful to behold!
