519. Esler, John G. A rhododendron king. Florists' Exchange 49: 169. 1920. — Mr. 

 W. K. Labar for the past fifteen years has collected native rhododendrons all over the Blue 

 Ridge from Pennsylvania to North Carolina, selling them, as well as azaleas, kalmias and 

 leucothoes, to parks, cemeteries and nurserymen. He has secured about 100 acres of wooded 

 hillside with northern exposure, and will specialize in the above mentioned plants and others 

 of similar nature. He is planting some of these by the thousand, using small collected plants 

 and seedlings. — L. A. Minns.

523. Griffiths, David. Producing domestic Easter lilies. Florists' Exchange 49: 134. 

 1920. — Notes on growing Easter lilies up to the present are added to Griffith's article in Flor- 

 ists' Exchange 48: 775. 1919. Nine batches of bulbs now in the greenhouses of the Bureau of 

 Plant Industry, Department of Agriculture, Washington, D. C, are mentioned, all of which 

 promise interesting data in this investigational work. It is suggested that each grower of 

 Easter lilies might advantageously do a little experimental work for himself. — L. A. Minns.

526. Matthews, Edwin. Transplanting a mammoth yew tree in winter. Florists' Ex- 

 change 49 : 83. 1 fig. 1920. — -An English yew, 25 feet in height, 30 feet in circumference, about 

 80 years old, and weighing, with the ball of soil attached, approximately 5 tons was moved 

 about one-half mile at Beverly, New Jersey, in January, 1918, and reset on the grounds of the 

 owner. It was raised out of its former situation by means of rollers and windlass, raised 

 onto a strong dray wagon by means of jack-screws, and drawn to its destination by six horses. 

 Adverse conditions made the task formidable, but subsequent good care makes the removal 

 appear to be successful up to the present. — L. A. Minns.

531. Sakamoto, Kiyoshi. The Japanese garden and how to construct it. Florists' Ex- 

 change 49: 61, 63, 138. 9 fig. 1920. — A Japanese garden must be made to appear as if it were 

 a piece of natural scenery. The noblest sentiment evoked comes from the correct placing of 

 each object — cottage, tree, herb or stone. Only large gardens can be successfully arranged 

 to present different aspects according to season. An ordinary garden may better be made to 

 appear much the same the year round. Evergreens are the foundation planting, set off by 

 deciduous trees. The main types of garden are described : (1) the plain-garden, reproducing 

 a plain, usually of considerable extent, good examples of which are the Tokiwa Garden and
