cigar & talk afterward. Young 
full of fun & enthusiastic about
birds. He has had Bearded Tits
in an aviary. Neither he nor
Saunders has ever heard the 
Bittern "boom". The bird is now
practically only a migratory visitor to 
England.
  Saunders & I finally left, walked
back through St. James' Park, thence
by cab to the "Zoo". It was more than
I had pictured it. Many of the
small British birds in aviaries, one
cage with Tits of several species supplied
with old stumps. A Nightingale
singing freely. A keeper said it was
a "hen bird." Saunders thought

from its various neighbours but both
admitted that a part was normal.
A brilliant, varied song long sustained [.]
Dined At Saunders' house at 7 P.M.
London
July 19 (Sunday). Cloudy with frequent
heavy showers. To 7 Radnor Pl. [Place] by cab
at 10.15 thence by cab with Saunders
to the Zoo where we spent forenoon.
Saw Night Heron brooding young in
nest. Also nests of several species of
Gulls, the young all out & nearly full 
grown. Gulls of various species cross
freely here; also Wood & Mandarin Ducks.
Many fine but noisy Cranes in pairs in
large, open enclosures. Wild sheep of several
species with artificial rocks on which
they skip about. Lion house said
to be finest in existence. Several 
superb Tigers & some fairly good Lions.
Movable tunnel to outer cage.
  Two Am. [American] Bison very good, pair of native
British cattle, a Gaur bull the largest 
known bovine & very rare.
  The Reptile house very interesting. A fair sand
Diamond rattle snake bred here. Introduced to
Mr. Bartlett son of superintendent. He gave
a live white rat to a huge carnivorous
