6 SUGGESTIONS FOR OWNERS OF WOOD LOTS IN NEW ENGLAND. 



The bur oak, chestnut oak, pin oak, post oalc, and swamp white oak 

 are generally more or less rare and of restricted local occurrence in 

 this region, so that they have no great commercial importance. 

 Owing to their great susceptibility to moth attack these trees should 

 be cut in every case where they are interfering with the growth of 

 better trees, or where there is an opportunity to replace them with 

 trees not so liable to moth attack. 



The white oak reaches the northern limit of its range in the gipsy- 

 moth infested region, yet it is one of the most abundant of the oaks. 

 Its foliage seems to be particularly desired by the gipsy moth, and it 

 grows very slowly. For these reasons it is not a desirable type for 

 growth in this region. 



The red, Hack, and scarlet oaks grow well and produce a valuable 

 class of material. - Where young, vigorous trees of these species occur 

 on good soil in mixture with other trees, they may be left, despite 

 their liability to gipsy-moth attack, providing that they are not 

 interfering with the growth of more valuable trees. 



Aspen, large-tooth aspen, and balm of Gilead can not tolerate shade, 

 and they grow well only where they have free access to plenty of 

 light. Scattered specimens in mixed woods may well be cut, but 

 pure stands, which occur occasionally, may be left to mature when 

 they are in demand for pulp or excelsior. 



Basswood occurs very much scattered in this region and grows to 

 advantage only on the best of sites. It may well be eliminated from 

 all others. 



Beech is more abundant in the northern than in the southern 

 portion of the region. It grows slowly and is likely to become defec- 

 tive before maturity. It is perhaps the least liable to damage by the 

 gipsy moth of any of the Class I trees. It is an excellent fuel and 

 should be cut heavily when in the way of faster growing and more 

 valuable trees. 



Paper lirch demands a large amount of light to grow well and is not 

 abundant in mixed stands. When it occurs in abundance, it is in 

 good demand for spool and novelty wood. It makes an excellent 

 fuel, and scattered specimens could often be cut to the advantage of 

 trees to be left. 



Tamarack is nowhere abundant in the infested region. When dry 

 it makes excellent kindling and a hot fire for a short time. 



TREATMENT OF TREES IN CLASS II. 



Class II is composed of eight species of trees on which gipsy-moth 

 caterpillars in their earliest stages do not feed, but upon which they 

 do feed in their later stages. Hence, if stands composed of these 

 species have in their vicinity no plants upon which the young cater-
