trous fruits. The leaves of these plants 

 turn yellow in the autumn before fall- 

 ing. 



Erica carnea. 



In the Shrub Collection this Heath 

 and its white-flowered variety are al- 

 ready in bloom. It is a common Euro- 

 pean plant which grows not more than 

 five or six inches high but spreads into 

 broad mats, and is the only one of the 

 true Heaths which is really hardy in 

 this climate. It is an excellent plant 

 for the edging of beds and for the 

 spring rock garden. 



AInus hirsuta. 



To persons who know Alders only as 

 they grow naturally in New England 

 these plants are small or large shrubs, 

 but the common European Alder, AI- 

 nus glutinosa, is at its best a large 

 tree; there are two large tree Alders 

 in the Pacific states and another in Ari- 

 zona and Mexico, and in Japan ana 

 eastern Siberia some of the species are 

 trees. One of these, Alnus hirsuta, 

 should be better known for it is per- 

 fectly hardy here and has grown more 

 rapidly than any other Japanese trees 

 raised from the seeds brought from 

 Japan by Professor Sargent in 1892. 

 In the Arboretum it is a shapely tree 

 already more than thirty feet high, 

 with smooth, lustrous pale gray bark 

 and spreading branches, and large dark 

 green leaves. In Japan it is often a 

 tree sixty or seventy feet tall with a 

 trunk two feet in diameter, and there 

 appears to be no reason why it should 

 not grow as large in this country. Of 



all the tree Alders in the collection it 

 has the most promise of long life and 

 large size, and it should prove a good 

 tree in the northern states to ornament 

 the borders of streams and ponds. In 

 Japan this tree furnishes wood used 

 for many purposes. 



The Cherries. 



The Japanese Cherry-trees in the 

 Arboretum promise a full bloom and 

 will be in flower in about ten days 

 when there will be an opportunity to 

 see here some of the most beautiful of 

 all spring-flowering trees.

FROST DAMAGES STRAW- 

 BERRIES IN MISSOURI. 



The Assistant Truck Crop Specialist 

 of the Bureau of Crop Estimates, 

 United States Department of Agricul- 

 ture, reports that a frost on May 8 

 injured a large area of the strawberry 

 section in southwestern Missouri. It 

 is estimated that the Aroma variety 

 were injured 80 per cent, and the War- 

 field 20 per cent., and tliat the probable 

 condition of the crop in the damaged 

 area is about 2.5 per cent. 



The acreage of strawberries in 

 Missouri was estimated by the Bureau 

 of Crop Estimates on April 24, 1917, to 

 be 6,950 acres, and, based on the con- 

 dition of the crop on April 1, a crop of 

 535,200 24-quart crates was forecast. 

 The condition of the crop on May 1 

 was reported to be 73 per cent.

PROPOSED NEW QUARANTINE 

 AGAINST GIPSY MOTH. 



An extension of the area in the 

 New England states under quarantine 

 against the gipsy moth and brown-tail 

 moth is being considered by the U. S. 

 Department of Agriculture, and a 

 public hearing on this question will be 

 held in Washington at 10 A. M., May 

 18, 1917, in Room 410, 1358 B St., S. W. 

 It is proposed to quarantine the fol- 

 lowing towns in adddition to the terri- 

 tory covered by existing quarantines. 

 New Hampshire: Chatham, Bartlett, 

 Waterville, Woodstock. Vermont: Hart- 

 ford. 



The result of this quarantine will 

 be to restrict the interstate shipment 

 from the quarantined area of nursery 

 stock, coniferous trees, forest plant 

 products, and stone or quarry products, 

 or any other article of any character 

 whatsoever capable of carrying gipsy 

 moth or brown-tail moth infestation, 

 except in accordance with regulations 

 prescribed by the Secretary of Agri- 

 culture.
