176 EXPERIMENT STATION. [Jan. 



BocUime. — This is the proprietary name of a suhstance 

 resembling Rau23enleini, a European product, and both have 

 been on the market for some years. Bodlime is an American 

 preparation, and has been used extensively for some time. 

 The directions which are furnished with Bodlime advise first 

 putting a band of tarred or sheathing paper eight inches wide 

 on young or thin-bark trees, and then aj)plying Bodlime to 

 the band. Over 90 per cent., however, of the trees examined 

 by us last summer on which Bodlime had been applied were 

 those of the smooth-bark type, ranging from two inches to 

 two feet in diameter, and in no instances were tarred or 

 slieathing paper bands applied. In j)ractically all cases this 

 substance had penetrated the bark and injured the cambium 

 layer. This injury, however, is in all probability not suffi- 

 cient to kill the trees in every case ; but more or less prominent 

 effects will be left on the trees for some years, as evidence of 

 the injury due to Bodlime. Some specimens of trees six 

 inches in diameter were pointed out which were killed with 

 Bodlime ; and practically all the Carolina poplars located on 

 the Fellsway, Maiden, w^hich have been treated with this sub- 

 stance, showed much injury to the cambium layer, resulting 

 in prominent swellings on the trees where this substance had 

 been applied. 



A number of small white maples (two or three inches in 

 diameter), which had been treated with Bodlime, appeared 

 in two or three weeks to have an abnormal cambium layer, 

 due to the penetration of the substance to the vital tissue. 

 In all these cases Bodlime was applied directly to the trees, 

 without paper bands. It should be noted, however, that the 

 mamtfacturers never intended that it should he applied to 

 small or smooth-barh trees unthout first handing ivith tarred 

 or sheathing paper, and the directions specifically state this. 

 AMien this is aj^plied to large trees, however, without paper 

 banding, it generally causes some subsequent slight disfigura- 

 tion of the tree. We believe, however, that Bodlime consti- 

 tutes a reliable banding substance, and can be applied to trees 

 if the directions of the manufacturers are followed, — to 

 first put on a band of tarred or sheathing paper. It should 

 by no means be considered a reflection on the manufacturers
