SAVE YOUR TREES 



FKOM SPLITTING 



Impending Dangen 



We cannot emphasize too strongly the use of proper precautions to prevent splitting 

 and to save the trees from destruction after they have started to split. There is no one 

 thing with which we have to contend, that threatens greater or more immediate damage, 

 than the splitting of crotch trees. Unfortunately, this trouble is not restricted to any one 

 locality; but it exists in a large proportion of the finest trees all over the land, and tens 

 of thousands of the most magnificent specimens every year are rendered shapeless and 

 valueless, from an ornamental standpoint, because no protective measures were taken in 

 time. 



Our long experience enables us to handle all these cases with complete success. The 

 method which we use consists of the chain and lag-hook system, together with special rein- 

 forcing braces, when the seriousness of the case requires it. This is the most simple, effec- 

 tive, and economical system that has ever been produced. 



Concerning this method, which was devised by Mr. John Davey. we take the following 

 extract from the article on Tree Surgery, by Dr. G. E. Stone, in Bulletin No. 125, of the 

 Massachusetts Agricultural Experiment Station: 



"In our estimation * » • the chain metho*! is superior since a rori is likely to break owing to its 



rigidity when the tree is swayed by the wind; whereas a chain, which is flexible, will stand the strain 



better. Steel chains are stronger than Iron rods, an d for this reason are better for use in such cases, 



besides being easier to place than a solid rod, as less attention has to be given to boring the holes."
