Grand total for patent bands, 313; for paper bands, 193. 



In the above tests, then, the patent bands excel tliose of thick paper more 

 than three e.xceeds two. 



Some bauds three inches wide were made of material such as is commonly 

 used for water proof cloaks. These were tested with the patent bands in the 

 manner above described. The test resulted in a catch of 30 moths for the 

 patent bands to 17 moths for the cloth bands. Perhaps thick cloth or cotton 

 flannel alone would do as well as the patent bands, but we have not compared 

 them.

 following results :

Total for patent bands, 251 ; total for paper bands on same trees, 75. 



The patent bands caught under similar circumstances a little over three and 

 one-third times as many moths as the bands made si-x inches wide of thick 

 woolen carpet paper.
