The Pied WagtaiFs nest containing the young Cuckoo was 

 remarkable from the fact that it had been built in a large 

 flower-pot containing a plant trained over an elaborate 

 framework^ leaving but small interspaces. Thus it was 

 certain that the egg of the Cuckoo must have been placed 

 in the nest with the aid of the bird's bill. Furtherj since 

 this plant was growing in a greenhouse, the Cuckoo could 

 only have discovered the whereabouts of the nest by watching 

 the Wagtails.
