Plate XXIV. An interior view of a pleached allee eight years after trans- 

 planting. Note the spacing of the larger plants of the European cork maple 

 at intervals of three feet, with "fillers" between each two of the larger trees. 

 Compare with Plate No. XXVII on page 175 for the exterior view. Open- 

 ings have been cut in the top of this allee to produce interesting spots of 

 sunlight on the walk. (See page 146. group XVI-D-a, also frontispiece)
