How mechanical bracing 

 restores strength to decayed trees 



THE internal woody tissue of the tree 

 has the same fiiuclion as the liones in 

 tlie human body — structural support. 



When this has been destroyed l>y decay, 

 Nature is helpless to restore it and the 

 tree, if neglected, u ill soon succumb to the 

 force of the winds, and im treatment can 



perinaiiPnt l.v sa\c it unless that treat iiient .siiu- 

 l)lio- seiciilificilly the str<'iiKth that lia.s IjRen 

 lost. 



Merely to till the cavity with eement 

 will not answer. The violent swaying of 

 trees by the winds maKes correct mechan- 

 ical hraciii« of iIpim,\ wpukened ca\itii'.s ahsu-

Correct mechanical bracing involves 



soniethinK more than Just fi\inK bars and Ixills 

 in the cav il.v. 



Kvery tree is ditVerent. and therefore 



th'' bracing.' of i ;n'h tree must (iillor from the 

 bracing u^fil in ail other trees, at least to some 

 extent .

The tree in photograph No. .'! required 



a combination of bolts and t'risscross bolts 

 with lock-nuts, torsion lods antl chains. 



The tree in photograph No. 1 was so 

 weak tiiat it regiiired a complicated and 

 complete system of internal bracing, in- 

 cluding cross-liolts. criss-cross bolts, iron 

 straps, anchors, torsifm nids. iron backbone 

 and ribs, lock-nuts, bolts above the crotch, plus 

 I'hains and lau- hooks higher up.
