 sary implements of the bee-hive. It is far superior to the 

 wooden-mat described by one or two writers. It is flexible 

 and porous, warm in Winter, cool in Summer. It may be 

 made of rye straw, or of what is called slough-grass, a tough 

 and coarse grass growing in marshy places, and abounding on 

 the bottoms of the Mississippi Valley. The mat shown in 

 fig. 73 is only about one inch thick.

 construction. It is well, in making them, to use strong 

 twine, soaked in linseed-oil; for the moisture, which escapes 

 from the bees in Winter, would soon rot the string.
