There is much apparent dissatisfaction with the ordinary 

 methods of sampUng ice. This laboratory is now using an ice 

 sampler based on the principle of a coal sampler. A brass 

 cyhnder, with the dimensions given in the diagram, has teeth 

 cut in the lower end. These teeth are given a set. The appa- 

 ratus fits into a carpenter's brace, which makes it possible to 





bore through a cake of ice with ease. The sample is not a solid 

 core but consists of small chips of ice which are easily pushed 

 out by means of a movable plug on the inside of the brass 

 cylinder. It is necessary to flame the tube a little before the 

 sample will slip out easily. With this apparatus, it is possible 

 to get a representative sample of ice without contamination.
