old shoots are cut with pruning shears or brush hooks, tied in loose 

 bundles and placed under cover. It takes a week for these bundles 

 to dry, and the bundles must be shifted frequently to prevent 

 mildew or other fungus attack. The dried bundles can be stored in 

 barns but piled loosely, so that there is a good circulation of air. 

 The best species for such feed are poplar, elm, basswood, birch, 

 ash, chestnut, buckeye and mulberry. Beech is not suitable, 

 neither are the conifers. A. B. R.
