'The White Poplar
This is one of the "trembling" poplars. It is a true native of Britain and is sometimes known as the Abele Tree. You are most likely to find it in moist woodlands, though it is by no means common ... The under surface of the leaves is covered with a thick white down, which shows up most attractively when the leaves are trembling in a breeze.
'The Cedar
This is the famous Cedar of Lebanon, which is mentioned several times in the Bible. It seems to have been introduced into Britain during the seventeenth century ... The tree is evergreen.... The leaves remain on the tree from three to five years. Cedars are usually grown in parks and gardens; you will rarely find them in woodlands. The timber is pinkish-brown and sweetly scented. Since Biblical times it has been highly valued as a building timber-the beams of Solomon's temple were made of Cedar-and for indoor furnishing and lining trunks and cases.'
