for weeks. Ground hard frozen.
  Garden birds. A Nuthatch & a

There again whole afternoon
when Outram Bangs & 
Fred Kennard came to 
look at birds & chat with me
for an hour or more. Soon
after they had gone Dr. Locke
appeared. He was with me 
until 6 P.M. he took another

24 [degrees] Fine
Brilliantly clear & frostily cold
with light but keen northerly wind.
Ground hard frozen at sunrise.
The repeated heavy frosts seem
to have little or no injurious
effect on early vegetation. Our
bed of squills in front of Museum
is now at it's best & very beautiful 
to behold. - a perfect carpet of
intermingling cerulean & green.
  Garden birds. A silent Robin; 4
Chickadees at suet; 2 Juncos, [male and female],
the [male] singing freely; 8 Fox Sparrows
one or more [males] in full, glorious
song at intervals through day;
small [female] Hairy Woodpecker, very tame
working ceaselessly at trunk of
dead sassafras; 6 Crows on wing;
2 Jays screaming; a dozen Grackles,
20+ House Sparrows.
  Rose at 1 A.M. Spent day in 
Museum & garden planting roses
& helping about chickens with
Percy. Gilbert [Robert A. Gilbert] motored to
Concord.
