COCKROACHES 125 



R. H. Lewis, in writing of a voyage taken by him 

 in 1835, gives an interesting account of the damages in- 

 flicted by cockroaches on board his ship in the following 

 words: "The ravages they committed on everything 

 edible was very extensive ; not a biscuit but was more or

Another traveler, Sells, gives a graphic account of

 egg-cases and leaving their feces and an intolerable 

 stench wherever they travel ; they also eat the corks of 

 bottled wine, cider, and porter, causing the liquid to escape. 

 This may, however, be prevented by dipping the corks in 

 a thick mixture of quicklime and water, the latter being

 They also eagerly devour parchment, which material is 

 consequently never used for wills, deeds, conveyances, or 

 other legal documents, which the insects would very quickly

 is accordingly rubbed over boots, shoes, and other leathern 

 articles to protect them from their attack." Like the
