on the successive trees of a row of standards, may be durably num- 

 bered on red cedar, after the following manner, to correspond with 

 a written register in a book. Fig. 155 shows the mode of notching 

 with a knife, to indicate the ten figures. To prevent mistakes by 

 getting them inverted, they are always read downwards on a stake, 

 or from the loop of a suspended label. The preceding figure (156) 

 exhibits a label on a tree marked with the number 47. 



Since the preceding chapter was written, the author has found 

 the best and cheapest labels for bearing trees to be those made of 

 sheet zinc, written on with a common black-lead pencil. If the 

 zinc is allowed to become slightly rusted, it will give a distinct 

 black mark, which will remain undefaced for many years, as a trial 

 of more than thirty years has proved, the name remaining un- 

 changed in the weather for that length of time. The sheet zinc is 

 to be cut in strips like that represented in Fig. 153, page 106, and 

 wound around a side -branch. This mode of attaching the label to 

 the tree is simpler and greatly superior to the common mode of 

 hanging it with a wire loop, which often wears off by the wind or 

 cuts into the bark.
