My botanical colleagues scrutinised the vegetation 

 on either side of the road by the early light ; the 

 others talked. I followed the party, a barometer 

 slung over my shoulder, a note-book and pencil in 

 my hand. 



My barometer, intended for ascertaining the height

The temperature grew colder ; olive and ilex 

 disappear, next vine and almond, then mulberry,

 enter on a monotonous region, stretching from the 

 limit of cultivation to the lower edge of the beech
