 woodland path brought us to Harrowgate Hill. Within a 

 few miles of this point are Coniscliffe and Aycliffe, which time

 should have seen the Permian rock rising boldly through the 

 glacial mantle, the thinly bedded limestone, with its small

After tea at Darlington, votes of thanks were accorded to 

 our hosts, and a visit was paid to the Backhouse Park, a 

 model of what a natural and cultivated recreation ground 

 may be made. 



The time of day and of year was not favourable for 

 observing bird-life, the following only being specially noted : 

 magpie, whitethroat, sand-martin, pied wagtail, willow-wren, 

 chiff-chaff, sedge warbler and stonechat. But on the other
