Atwater. those made of alternate strips of metal and wood, with a rim giving a bee- space above the slats. Not only the old plain excluders interfere more or less with the accuracy of the bee-spaces, but in removing they are easily kinked, so that quite a per cent of them "leak" queens. But the factory-made, slatted exclud- ers are too frail for general use. They also contain more openings than neces- sary or useful. In Cut A we see an exc'.uder such as we use, with very good results. The rim is 5^-inch thick (about ^-^-inch thicker than the rims of the excluders regularly supplied by the factories.) The slats are ^-inch thick. about 234-inch wide and grooved on their edges, so that .five strips of two-row zinc are used. AH wooden parts being ''g-inch thicker than in the regular goods, and slats over twice as wide, makes these excluders stronger and more dur- able than the regular goods. The corners are not halved. This ex- cluder also contains the feature valued by R. C. Aiken; a row of holes at the outside, so bees can pass directly up the hive- side into the super. In Cut B, we have an example of our latest excluders, of which we have 200 in use. It is almost the same as the other, except that the corners of the rim are halved, and there is no row of openings at the extreme outside. This is even stronger and more durable than the other style, as halv- ing the corners permits more thorough nailing, and the side strips of the rim are also firmly nailed to the outside ^- inch slats. Wishing to test the new wire excluders, we put two rows of it in each excluder, as shown. We think that the wire is better than zinc, as by actual measurement it is more accurate, and no doubt permits the bees to pass more freely. The only reason why more rows of openings are used in this excluder, is that we could get the nar- rower strips more easily than wider ones. I
