244 Insects Injurious to Vegetation. [Oct., 



dieth so dieth the other — the spirit (breath) of men goeth up- 

 ward, and the spirit of a beast goeth downward to the earth." 

 Where, exultingly exclaims a modern zoologist, is the soul of 

 the homunculus? Do we not see it built up before our eyes, 

 maturing with the body, decaying with its decline, and finally — 

 ex nihilo nihil, in nihilum redit — going with the last expira- 

 tory collapse into annihilation? The argument is but a soph- 

 ism, a post quod non. What if the soul in its existing phases 

 is indissolubly associated with a corporeal mechanism, is it 

 therefore an inseparable nonentity? Is that too much for the 

 Author of Being to reconstruct and modify what himself ori- 

 ginated and contrived? If indeed " shadows, clouds and dark- 

 ness" environ and obscure this heaven-born emanation — " se- 

 mine ab acthereo " — what shall dispel the euthanasial solace in 

 its prospective transmigration to the fadeless elysian of cherub- 

 im and seraphim, where shines that " holier light, offspring of 

 heaven?" 



" Bright to the soul Hope's seraph lands convey 



The morning dream of life's eternal day ; 



Then, then the triumph and the trance begin, 



And all the phcenix-spirit bursts within !"

THE HESSIAN FLY. 

 The insect wdiich we are about to consider, has for a long 

 period been, at times, a severe scourge, in every district of our 

 country. It is more formidable to us, says Dr. B. S. Barton, than 

 would be an army of twenty thousand Hessians, or of any other 

 twenty thousand hirelings, supplied with all the implements of 

 war. Hence it has forced itself prominently to the notice both 

 of agriculturists and men of science. No other insect of the tens 

 of thousands that teem in our land, has received a tithe of the 

 attention, or been chronicled with a tithe of the voluminousness
