One was perfectly sound, but the other had been attacked, par- 

 ticularly at the water line. The analyses were made to determine 

 whether the difference in the durability could be accounted for by 

 a difference in the amount or character of cresote in the wood. 



"The piles had been treated by the old Bethell process, but no 

 treating records are available, nor is it known where the creosote 

 was obtained." 



"Practically no light oils (oils distilling below 205° C.) were 

 found in the piles after their long period of service. If originally 

 present, they were lost by volatilization and leaching. 



"The creosote in the pile which was perfectly preserved con- 

 tained originally at least 40 per cent, of napthalene fractions, a 

 large proportion of which remained in the wood. The creosote in 

 the pile, which was less perfectly preserved, contained little or no 

 napthalene. 



"The pitchy matter, which on distillation formed the residue 

 above 320° C, is seemingly of an inert character and little ob- 

 jectionable to the teredo. A heavy treatment with creosote con- 

 sisting largely of this material did not entirely save the pile from 

 attack. 



"Loss of oil from that portion of the pile in the water, in the 

 case of the creosote in pile No. i [the one that was not attacked], 

 which is a pure coal-tar creosote, apparently occurred only in the 

 fraction distilling below 225° C."

Second Growth Hardzvoods in Connecticut. By Earl H. Froth- 

 ingham, Bui. 96, U. S. Forest Service, Washington, D. C, in co-

"In dealing with forests among the essential things to know are 

 the rate at which they grow, the value of the standing timber for 

 different uses, and the method of management which will give the 

 maximum yield of the most valuable material in the shortest time. 

 To tell these things for the forests of Connecticut, especially for 

 the predominating types — second -growth chestnut, oak, and 

 mixed hardwoods — is the purpose of this bulletin." 



This purpose is well carried out in the publication which is 

 divided into four parts as follows :
