298 AGRICUI^TURi; OF MAINE. 



The ground plan shows a building 46 by 32 feet, outside 

 measurements, giving a storing and packing room 8 by 30 feet 

 and a storage room of 36 by 30 feet with a capacity of about 

 800 barrels, provided th(; barrels are set three tiers deep. 



We would recommend placing this building on a concrete 

 foundation with a floor of the same material making it rat- 

 proof. Have a wall space of one foot filled with sawdust. 

 Board up on outside, and shingle or clapboard with sheathing 

 paper between. Sheath up on inside with good matched 

 boards. Leave spaces at back end for three windows, these to 

 have three sashes to each window. Have good double doors 

 in front and a single sliding door in the partition. 



For ventilation have openings on each side just under the 

 eaves so arranged as to close up securely on outside and inside. 

 The floor overhead should be of matched boards above and 

 below, at least six inches apart, filled in with sawdust. 



PRINCIPAL INSECTS OF THE ORCHARD. 



INFESTING THE ROOTS. 



Woolly aphis, Schizoneura lanigera. This insect leads a dual 

 life, existing on the roots, producing gall-like enlargements or 

 swellings, also on the trunks of small trees especially around the 

 scar where limbs have been pruned or in the small crotches of 

 the branches. For a further description I will quote from my 

 annual report of 1906. 



"They are small reddish-brown lice, and as generally seen, are 

 covered with a long white woolly substance. These appear in 

 patches on the limbs of the trees, often resembling mildew in 

 general appearance. They also live in colonies on the roots of 

 the same tree where they form gall-like swellings of varying 

 sizes as shown in Fig. 15. They are much more destructive 

 when found on the roots as they sap the life of the tree directly 

 from its source. 



The insect passes the winter either in the egg form in crevices 

 in the bark of the trunk, or in the adult stage in the gall-like 

 formations on the roots. 



In the spring the eggs hatch producing the agamic female and 

 these give birth to living young as do those of the San Jose 

 scale. This continues through the summer when the winged 

 form appears. These fly to other trees and produce male and
