hedgerows, investigating strange woodlands, exploring un- 

 familiar ravines, threading the maze of herb and shrub along 

 pond and stream, he is ever on the margin of adventure. Per- 

 chance he may find a rare plant never reported from the re-

 is still the pleasure of finding the very first flower of its kind 

 to open, the possibility of encountering a noteworthy varia-

 in new settings, not to speak of the mere joy of existence 

 when the trees are in leaf, the birds in full song, butterflies 

 flitting over meadow and thicket, and the earth spangled with 

 flowers.
