other tree. It is much subject to the attack of the San Jose 

 scale, which has destroyed a great many trees. 



Purple-leaved Oak {Quercus pedunculata, var. atropur- 

 purea). — The characteristic of strength typified by the oaks 

 makes any of the species of interest, and if in addition to this 

 character they possess strikingly beautiful features they 

 become all the more valuable. This tree has dark purple 

 or bronze-green foliage all summer, is moderately vigorous 

 in growth, and very desirable. 



Golden-leaved Oak (Q. p ., var. Concordia). — This is 

 perhaps the best of the golden-leaved oaks, and is very 

 beautiful when the leaves first unfold, but it loses some- 

 thing of its freshness and beauty as the season advances. 

 Its chief value consists in the use that may be made of it 

 in toning down the extreme shades and tints of other trees. 



Golden-leaved Japanese Maple {Acer jap., var. aureum). 

 — A most beautiful tree for planting with the purple-leaved 

 forms of A. palmaHwi. 



Golden Elm {Ulmus campestris, var. aurea), Fig. iio,(i). 

 — This beautiful tree is of slow growth, but planted in 

 moderately rich land succeeds well and is worth repeated 

 trials to secure the establishment of even a single specimen. 



Chinese Catalpa {Catalpa Bungei), Fig. 113.— A most 

 interesting round or umbrella-formed tree with large, bright- 

 green foliage. In shght shelter and in a deep, warm, sandy 

 loam it proves hardy and valuable.
