THE DIRECTORS' MEETING

They can be destroyed on the ground by pouring hot 

 water over them or by spraying them with a strong 

 solution of kerosene emulsion. Banding ehn trees, so 

 commonly practiced, prevents the grubs from crawling 

 down the trees and defeats the very purpose intended by 

 the bands. 



4. Remove the cocoons and egg masses of the Tussock- 

 moth and insects of similar habit. These can be scraped 

 off with wire brushes or may be destroyed by an appli- 

 cation of creosote on a sponge or rag. The former is 

 preferable. 



5. The locust miner is now feeding ravenously on 

 black locust trees and in some cases even on oak, linden, 

 and fruit trees. Spraying the leaves with arsenate of 

 lead, 1 pound to 10 gallons of water will destroy the 

 insects. 



6. The white pine weevil may now be found in grub 

 form boring in the shoots of white pine trees. The af- 

 fected twigs turn yellow and are easily noticeable. Timely 

 removal and destruction of infested branches is the 

 remedy. 



7. This is the time when borers may be seen burrow- 

 ing in peach trees or in oaks, maples and other trees. 

 For those borers that work in peach trees and other trees 

 that exude a gummy substance when injured, employ 

 the method of cutting out the grub with a knife. Any 

 attempt to inject a liquid in the cavity will be hindered 

 by the gummy exudation. For the maples, etc., where 

 the orifice leading to the grub is clear and large, inject 

 carbon bisulphide and clog the orifice with a bit of soap 

 or putty immediately after the injection. The fumes gen- 

 erated by the liquid will enter every crevice of the bur- 

 row and destroy the insects within. 



8. August is a good time to begin thinning out wood- 

 lands where young trees are crowding each other or 

 where young trees of better form are to be encouraged 

 by the removal of surrounding trees of inferior quality. 

 This work can be best accomplished while the leaves are 

 still on the trees. 



9. The latter part of August is the period to begin 

 pruning trees and cutting off all dead branches. The 

 distinction between live and dead branches can be made 

 more readily before the foliage drops. The results will 

 be more certain and the work will be accomplished with 

 greater ease and less skill than if it were done in winter. 



NOTES 



1. The sycamore blight (gleosporium nervisequum) has 

 exacted a heavy toll this year, especially on the native 

 species. Complaints have come in from Rome, \. Y., 

 and from all over Long Island. Early spraying with 

 Bordeaux mixture has controlled the blight in Prospect 

 Park this year and four years ago. 



2. The hickory bark borer is very noticeable this year 

 as far west as Buffalo, as far north as the Katskills and 

 east in Connecticut. Seven years ago it was serious only 

 in the vicinity of Brooklyn. 



3. The forest tent caterpillar has shown itself more 

 numerous this year than ever before. Whole forests 

 were devoured on many parts of Long Island and in 

 Pennsylvania and New York States. The insect is now 

 in its egg state. 



4. The moisture conditions have made this season a 

 favorable one for vegetation in the East. 



5. Mr. R. Brook Maxwell, city forester of Baltimore, 

 reports a heavy invasion of the army worm in Cecil 

 County and recommends the following formulas for 

 spraying against it : 



The first is a preparation of 2 pounds of arsenate of 

 lead in powdered form mixed with 50 gallons of water. 

 This should be applied to the seat of the army worm's 

 efforts. If the lead is used in paste form, 5 gallons of 

 paste are required to 50 gallons of water. 



Another preparation that has given excellent results 

 is made from 10 pounds of ordinary bran, one-quarter 

 pound of Paris green, or arsenate of lead and a pint of 

 molasses or other sweet substance such as sugar. This 

 should also be spread over the lawn or applied otherwise 

 to the center of the worm's activities. 



The Directors' Meeting 



DIRECTORS of the American Forestry Associa- 

 tion will hold their fall quarterly meeting at the 

 Profile House, X. H., on September 1 and 2. 

 This meeting will be preceded by a visit to Boston on 

 August 31, where the Arnold Arboretum will be in- 

 .spected and the party will be met by officers of the 

 Massachusetts Forestry Association and by Boston 

 members of the American Forestry Association. 



The directors will breakfast at the Algonquin Club 

 and will leave there for the Arboretum at 9.30. The 

 party will leave Boston at 12.30, reaching the Profile 

 House that evening. 



The annual forestry conference in the White Moun- 

 tains under the auspices of the Society for Protection 

 of New Hampshire Forests and of the State Forestry 



Commission, will start on the evening of September 1 

 at the Profile House and the American Forestry Associa- 

 tion directors will attend this gathering and will extend 

 an invitation for the appointment of delegates to be 

 present at the conference with Secretary of Agriculture 

 Houston at Washington, at 9 a. m. on September 22. 

 This conference will be for the purpose of presenting 

 to Secretary Houston arguments in favor of extending 

 the Weeks Law appropriation for the purchase of Fed- 

 eral Forest Reserves in the White Mountains and South- 

 ern Appalachians. 



It is hoped to have Congress provide an appropriation 

 of $10,000,000 for this purpose, to be used during the 

 next five years.
