These results have been verified by more or less extensive inspections 

 in all of the larger towns of the State, and while a few hard maples 

 have been found infested with the Gloomy Scale, our inspections 

 would show that hard maples are at least highly resistant to the 

 attacks of this scale. We have frequently found a hard maple entirely 

 free from Gloomy Scale growing between two soft maples which were 

 dying from its attacks. This suggests that the present condition 

 will naturally correct itself in time, because people will cease to plant 

 the quick growing soft maples and set in their stead the slow growing 

 resistant hard maples. In this connection the following list of host 

 plants which have come under our own observation is given: 



Apple, (Pyrus malus L.) Several young trees growing under the 

 overhanging branches of badly infested red maples found slightly 

 infested. 



Red Maple. (Acer rubrum L.) Generally infested. 



Silver Maple. (Acer saccharinum L.) Uniformly and badly 

 infested. 



Sugar Maple. (Acer saccharum Marsh.) A few scattering indi- 

 viduals found infested, mostly very slightly. 



Box Elder. (Acer negundo L.) A few infested. 



Buckeye. (^Esculus glabra Willd.) Slightly infested. 



Japanese Chestnut. (Castanea sativa.) Badly infested. 



Sycamore. (Platanus occidentalis L.) Slightly infested 



Water Oak. (Quercus nigra L.) A single tree slightly infested. 



White Oak. (Quercus alba L.) A few trees slightly infested. 



Iron-wood. (Carpinus caroliniana Walt.) A single badly infested 

 tree. 



Willow. (Sahx sp.) A small badly infested tree found along a 

 stream in Lincoln County. 



Cottonwood. (Populus deltoidea Marsh.) Slightly infested tree. 



American Elm. (Ulmus americana L.) Slightly infested.
