laid over the channel and then a stout wire, which, being 

 sharply struck with a hammer, causes the zinc to take 

 the desired form. The accompanying illustration re- 

 quires little explanation. 



1. A good border label with grooved stem. 



2. The same as last but smaller. Was taken from a 



bed and photographed after many years' ex- 

 posure, without cleaning or preparation. 



3. A convenient label for pots or border, the lower 



part grooved. 



4. A good label for hanging to a branch. The end 



is rolled and the wire put through the tube thus 



formed. 

 5- A good label (with long wire stem) for aquatics or 



for scrubby vegetation, above which the label 



stands clear. The label swings on a coil of the 



wire and is easily removed. The metal is doubled 



before the hole is made. 

 6. A label good for trees. The bend over at the top 



prevents the soiling of the face by birds. 

 7 and 8. The pieces cut off in making Nos. I and 2. 



They make good pot labels as they are. 

 9. The iron block and stout wire for forming the 



groove, 

 io. The shears. The lower vertical part goes into a 



socket at the side of the bench. 



Selection of the most ornamental species for general 

 cultivation, all easily grown, the Oncocyclus section 

 excepted. 



N.B. Garden forms are given under the species 

 to which they respectively belong in Part II.
