The little Jenny Wren and Golden-Crested Wren are 

 great friends to gardeners, for they catch multitudes of

 swallows are, of course, also useful. In conclusion, I may 

 say that I am indebted to the pages of " Farm Insects," 

 by John Curtis, for some of the facts set forth in these 

 two chapters on insect pests and insect friends.
