THE McCANN SAMPLER. An improvement on all others. The heavy metal 

 base forms the sampler support and pan stop, eliminating the clumsy frame 

 work heretofore used. The short riffles, easily cleaned, reduce to a mini- 

 mum the danger of salting. This sampler is especially constructed for 

 rapid work. Made in three stock sizes, as follows: 



Size, inches 4x6 6x10 8x12 



Price, each $8.00 10.00 12.00 



Larger sizes made to order. Prices on application.
