In the ease of the treeskilled at Marshall Hall, galleries made by borers had honeycombedthe wood beneath the section of hark riddled by the sapsuckers. Only 2 stomachs of sapsuckers were collected. They were takenduring the middle of November, L899 and L900, and contained severaldung-beetles (Aphodius) and the fruit of woodbine and red cedar.
