especially the numerous varieties of Japanese Maples 

 (Acer palmatum and A. japonicum), these, as well as 

 the Mandshurian Acer Ginnala, turning to various 

 shades of red. The Common Sycamore and Norway 

 Maple change to yellow, but Schwedler's variety of 

 the latter becomes red. Other trees that deserve 

 mention are Amelanchier canadensis, whose foliage

 reuterta japonica, soft yellow ; Pyrus Torminatis, bronzy 

 red ; Ginkgo biloba, pale gold ; Cladrastis tinctoria, 

 yellow ; Parrotia persica and Hamamelis, bronzy red 

 and yellow. The Common Beech is nearly always 

 beautiful, changing first to yellow, then to warm 

 brown tints. Clerodendron trichoiomum is a small 

 growing tree that should have a place wherever 

 beautiful autumn foliage is desired. Among Conifers 

 the yellow-leaved variety (aurea) of the Scotch Pine 

 is remarkable in retaining its colour during the 

 winter months only, becoming green in spring and 

 summer. Retinospora squarrosa and Cryptomeria elegans 

 turn bronzy red in winter. The warm red-brown 

 tints of the deciduous Cypress are charming.

 which turn red. The Venetian Sumach, R. Cotinus,
