THE SOUTHEKN PIKE SAWYER. 45 



PECUNIARY LOSS. 



Approximately 25 per cent of the lumber in eju li lo<^ infested by 

 the S}U\yer is seriously (lamao:etl. The ])ecuniary loss may therefore 

 be computed as follows: Lundjer undamaged by insects was worth, 

 in 1908, $19 a thousand feet b. m. at the mill in southern Mississippi. 

 "Wlien infested by the saw^'er the 25 per cent damaged was reduced 

 in value to S7.50 a thousand. 



It is estimated that in the storm of September, 1908, 2,000,000,000 

 feet of timber were blo\\qi do^v^l. In the 1907 storm, in Alabama, 

 800,000 feet were blown do^\^l, and in the storm of April 24, 1908, 

 which passed through two or three States, 180,000,000 feet were 

 blowii doAVTi. This gives us 2,180,800,000 feet of tunber blown 

 down by these three storms. Practically all of this storm-felled 

 timber was damaged by the sa\^yer. 



As stated above, 25 per cent of each log damaged is reduced from 

 $19 a thousand feet to $7.50 a thousand feet; therefore we may 

 consider that 25 per cent of the whole, or 545,200,000 feet b. m. 

 was reduced from S19 a thousand to S7.50 a thousand. At $19 a 

 a thousand this amount of timber would be worth $10,358,800. 

 At $7.50 it would be worth $4,089,000. The difTerence between 

 these two sums is $6,269,800. Therefore, if this timber had been used, 

 or could have been used before the sapwood decaj'cd, the last figure 

 given woidd represent the total loss chargeable to the sawyer. 



CHARACTER OF THE INSECT. 



Adult. — The adult (fig. 14) is an elongate beetle varying from 

 16°^™ to 31.5'"'" in length and from 5 to lO"""" in width. The color 

 is a mottled gray and broA\ai. In the male the horns, or anfennne, 

 are verj^ long, often being two or three times the length of the beetle. 

 In the female they are much shorter than in the male, but are still 

 somewhat longer than the body. 



Egg. — The egg (fig. 15) is elongate-oval, approximately 4'"'" long, 

 by 1.5'"'" in diameter at the middle. The color is opaque white. 

 There are two distinct coverings, which correspond to the outer and 

 inner shells of the egg of a fowl. The outer is kno^^-n as the chorion 

 (fig. 15, a, d), and the inner as the amnion (fig. 15, h). At one end 

 is found a depression or little round hole, which is kno\m as the micro- 

 pyle (fig. 15, c). Under a high-power microscope the chorion is seen 

 to be verj' prettily sculptured on its outer surface (fig. 15, e). 



Larva. — ^The larva (fig. 16) is an elongate, footless, white grub with 

 powerful jaws or mandibles for boring through the wood. The size 

 varies considerably in diderent individuals and according to age. 

 The largest at maturity have been found to measure slightly over 

 60'"'" in length and 9'""' in i)rcadth at the broadest pomt (the pro-
