SUGGESTIONS FOB OWNERS OF WOOD LOTS IN NEW ENGLAND. 7 



pillars can feed, the stands may safely be considered immune from 

 attack. Trees of this class may be grown safely in mixture with trees 

 of Class IV. 



Stands composed largely of one or more of the species of this class 

 can be made immune from gipsy moth attack by removing the trees 

 which may provide the young larvae with food. There are many 

 places where a considerable amount of cordwood could be cut most 

 advantageously with this object in view. 



Great care should be taken to protect and preserve young white 

 pine and red pine, especially when they occur on poor soils. They 

 often grow well on such soils, and if they are present the associated 

 hardwoods which do not grow well on such sites, and which may be 

 subject to caterpillar attack, may be cut beneficially. Red pine is 

 not affected by the white-pine blister rust, which is spreading very 

 slowly among the white pines. If young white pines are given a fair 

 chance to grow, they will probably reach maturity before being 

 seriously affected by the rust. 



Chestnut grows well and yields a valuable product, but unfortu- 

 nately is subject to attacks of the chestnut blight. It makes a poor 

 grade of fuel, but with a shortage of the better grades an opportunity 

 doubtless will be afforded for the disposal of a considerable amount 

 of this species. 



TREATMENT OF TREES IN CLASS III. 



Class III is composed of 20 species which are not particularly 

 favored by gipsy moths, but upon which a small proportion of the 

 larvae may develop. Stands composed of any trees of this class 

 alone or mixed with trees of Class IV, but containing no trees of 

 Class I, would maintain only slight infestations and rarely, if ever, 

 would be defoliated. 



Blue beech, choice cherry, wild red cherry, hop hornbeam, and sassafras 

 have no particular commercial value ordinarily and could well be con- 

 verted into cordwood at this tune. 



Black cherry has considerable commercial value, but its occurrence 

 is generally rare. American elm and slippery elm are also generally 

 scattered. Unless growing in very good soil, these trees could well be 

 cut. Cottonwood, bitternut hickory, Hack gum, silver maple, and silver 

 poplar are rare. Bitternut hickory makes very good fuel, but silver 

 maple is not so good. The cutting or preservation of these species 

 will have little effect in any respect. 



The remaining trees of this class, namely, black and yellow birches, 

 mockernut, pignut, and shagbark Jiickories, and red and sugar maples 

 can be grown in comparative safety as far as the gipsy moth is con- 

 cerned. The yellow birch, hickories, and sugar maple make the best
