This is an essay read before the Pennsylvania State Horticultural Association by Mr. Simon R. Eby, and now published in pamphlet form. It is an excellent plea for the birds. There is of course another side to the story, but that is not Mr. Eby's theme. The birds which receive the chief friendly notices are swallows, night-hawks, purple martin, king bird, rock pewee, wood pewee, Baltimore oriole, orchard oriole, wood thrush, vireos, some warblers, wren, blue bird, titmouse, chickadee, mocking bird, robin, cat bird, black bird, meadow lark, chipping sparrow, song sparrow, indigo bird and the wood-peckers. Mr. Eby repeats the belief of many ornithologists that the sap-sucker is searching for insects when it makes the innu merable holes, like honeycombs, on many trees This must be a mistake. There are certainly no insects in many scores of branches which are riddled by the bird, and it is incredible that birdly instinct should lead to the loss of time and hard labor involved in the boring of thousands of useless holes. But granting that these numberless holes are for the purpose of hunting for one insect it can make little difference to the tree how the holes are made.
They are just as bad for the tree as if an insect made them.
