Isaac Hicks & Son, West bury Station, N. Y. Deciduous Trees 



These big, old Catalpas are offered at low prices. 

 They are strong, healthy, broad and shady. With 

 Silver Maples, they will give the most foliage for the 

 expenditure of any tree we offer. 



Chestnut Castanea 



American. Castanea Americana. This is an 

 important timber tree of Long Island ; in its 

 maturity a majestic tree remarkable for the 

 breadth and depth of its shade. 



A serious fungous disease is killing the 

 Chestnut trees in the forests of Long Island. 

 It frequently kills 20 feet of the top or may 

 work lower down on the trunk. It starts 

 from a spore in a crotch or wound which 

 sends out mycelium or threads of the fungus 

 penetrating the bark next the wood. In a 

 few months it girdles the branches and the 

 leaves turn yellow and drop. A tree appar- 

 ently healthy in June may be half-dead in 

 August. The fungus produces spores in 

 orange pustules or jelly horns on the dead 

 bark. There is no treatment known, except 

 to cut off affected branches and cut out 

 dead bark on the trunk, and larger branches 

 before they are girdled. Cut an inch or 

 more beyond the edge. 



In similar work on pear blight in Cali- 

 fornia, it is advised to disinfect tools and 

 wound with corrosive sublimate, one to 

 one thousand. This remedy, painting the 

 cuts with tar, and spraying with fungicides, 

 have not been thoroughly tested. The cut- 



American Chestnut, continued 



ting is practical on isolated trees, but in 

 the forest is very expensive. 



Dr. Haven Metcalf, Division of Forest 

 Pathology, United States Department of 

 Agriculture, is experimenting along these 

 lines in the young orchard of Mr. R. Dudley 

 Winthrop, Westbury Station, L. I. In tnis 

 orchard and that of Mr. Charles R. Steele, 

 and in our Nursery, he finds the Japanese 

 Chestnut immune. 



The disease is new to science. Dr. Mur- 

 rill, of The New York Botanical Garden, 

 Bronx Park, named it in 1906, Diaporthe 

 parasitica. One hope is that, like many 

 other plagues, it will go in waves and, later, 

 largely disappear. 



It may be a blessing in disguise. On 

 many Long Island private estates the 

 woodlands will be more beautiful if gradu- 

 ally thinned out, according to the principles 

 of landscape forestry described on page 4. 

 Ninety-nine per cent of owners have not 

 the knowledge, imagination and courage 

 to do it. Now the diseased trees have to 

 be cut, and the Oak, Hickory, Tulip and 

 Dogwood will have a chance to develop 

 into broad, handsome trees. 



'Cut the trees before they rot. Take them 

 to a saw-mill, or get a portable saw-mill to 

 cut them into framing timber or other lum- 

 ber. Show that Long Island is not entirely 

 dependent on imported lumber. There is 

 also a market as telephone poles or cord 

 wood. Felling trees and dragging out logs 

 does some damage to other trees, but it soon 

 disappears. 



The White Dogwood is one of the best for planting by the hundred. 

 The broad palms of foliage make a picturesque outline with deep 

 shadows.
