December.
  The weather during December has been very mild. During
but five days, the 10th, 12th, 14th, 15th & 16th, did the
mercury fall below the freezing point. 10+ degrees on the 10th was
the lowest recorded, while a maximum of 58+ degrees was reached on
the 24th. On every day except the 10th, 12th, 14th, 15th,
16th, 17th & 27th, the mercury rose to 35 degrees or more, while on
31st, a record of 45+ degrees or more was reached. An average minimum
of 30+ degrees and maximum of 40+ degrees will give an idea of the mild char-

between daylight and dark. While no records of the night
temperature were made, the nights were, with but few excep-

  Very light snow, rapidly disappearing, fell on the 4th,
11th, 15th, 16th & 28th. Rain fell on the 4th, 28th, 30th &
31st. All the rest of the month was clear or cloudy, while 
on the 14 days the sun shone brightly from its rising to its
setting. These days were, 1 - 2 - 3 - 8 - 10 - 12 - 14 - 17 - 
18 - 20 22 - 27 - 29 - 30. There was a fog on the night of
 the 24th followed by freezing, and the next morning, Christmas
day, under a bright, clear sky, every tree glistened with di-
amonds, formed of the frozen drops.
  A strong S.E. gale blew on the 4th, and on the 10th there
was a sharp N.W. wind, but with these exceptions there have
