whole added afterwards. Preserve the mixture in a well corked 

 bottle, shaking it repeatedly at first, and keep the ccrk downwards 

 to prevent the escape of ammonia, and it will remain fit for use for 

 years. 



If the pieces of zinc are suspended by copper-wire, it should be 

 firmly twisted round the zinc so as not to remain loose 

 (Fig. 151), or else the constant motion from wind will 

 soon wear off the wire. The wire should be nearly as 

 large as a small knitting-needle, to prevent cracking off 

 by long use. The loop should be large, and pass round 

 a side-shoot, instead of a main branch, to prevent the 

 danger of cutting in by the growth of the tree ; and 

 should be attached below a small fork, to prevent its 

 blowing off the end of the branch. 



The wire may be wholly dispensed with by the follow- 

 ing contrivance : cut the zinc into long triangular strips, 

 half an inch wide and from six to ten inches long. 

 Draw the narrow or slender end round the twig, bring 

 it through a hole punched midway between the ends, 

 and clinch or twist it with the fingers or a small pair of pincers 

 (Fig. 152). These labels may be cut and punched 

 by a tinman .at a cheap rate. 



A good, durable, and cheap label, is made of 

 sheet tin. Cut the tin in strips about six inches 

 long, somewhat in the form of a wedge, about a 

 fourth of an inch wide at one end, and three-fourths 

 at the other. Write the name near the wide end, 

 with any sharp steel 

 instrument, as an 

 awl, or end of a file 

 ground sharp, bear- 

 ing on hard enough 

 to go through the 

 tin coating, so as to 

 reach the iron. In 

 a few months the 

 rain, by penetrating 

 to the iron, will rust 

 it, and make the 

 name quite conspicuous. The label is then attached to the tree by 

 bending the narrow end once about a side limb (Fig. 153). As the 

 tree grows this coil will expand, and not cut the bark. On this
