BEES AND BEE-KEEPING. 
will be better that I should give the exact measure- 
ments of the Heddon, premising simply that these 
are absolutely empirical. The body-boxes (dd) are 
each 5jin. deep by iplin. by I3in. outside, the 
ends |in. and the sides fin. thick. Before nailing 
together^ the inner part of the top and bottom edges 
is rabbeted down (r and r', Fig. 34) ^in., leaving a 
rim fin. wide only, so that, when the boxes come 
together, they touch only at the fin. rim, while the 
-^in. rabbet in each make together a full bee-space (ds)

of fin. This principle of allowing a half bee-space 
above and below, in each horizontal section of the 
hive, so that the needed fin., and no more, is given 
in any possible combination, is a salient and new 
feature in the Heddon. The bottom board carries a 
lath (/, Fig. 33), fin. deep, and fin. wide at its upper 
edge, upon which the hive rests, so that a larger, but not 
excessive, bee-space is made beneath. An entrance 
{e) is thus secured, which is regulated by the Lang- 
stroth blocks {/d, lb'). Since the body-boxes are
