DIPPING TUBES COLLECTING CASE. 131 



bottle of water, a tube or tubes of the form shown in 

 Fig. 117 will be found necessary. They may be cut from 

 ordinary glass tubing by making a cut with the edge of a 

 three-square file, and breaking it in two with the fingers. 

 The sharp edges should then be fused by holding in the 

 flame, finally allowing to cool gradually. The bent tubes 

 may be made by taking a length sufficient for two tubes 

 and softening the middle portion in the flame of an 

 ordinary gas burner or spirit lamp, and when sufficiently 

 softened the two extremities are to be pulled asunder so as 

 to form a couple of tubes of the form of B, Fig. 117, they 

 can then be cut asunder with the file and the edges fused. 

 The form A is produced in a similar manner, the softened 

 portion being drawn out obliquely. 



It is a great mistake to load oneself with a host of 

 paraphernalia. The labour of carrying a heavy pack often 

 destroys what might otherwise have been an enjoyable 

 excursion.

A set of half-a-dozen small corked bottles or tubes, and 

 as many small tinned boxes, will complete the collector's 

 outfit. A small but handy pocket collecting case was 

 introduced several years ago by Stanley, of London. (See 

 Fig. 1 1 8.) 



The objects having been collected, the next thing is to
