138 Canna Bihorelli. 



for although trees worked from three to eight inches high will throw 

 out roots from every part of the quince when it is buried below the 

 surface, yet the lower roots would be too deep for their highest health, 

 especially in soils at all cold or wet. 



The root of the quince being tenderer than that of the pear, requires 

 special protection in winter, especially where the ground is liable to 

 freeze hard when not covered by snow. A good covering of litter of 

 any kind, or coarse, strawy manure, is needed, and the latter will afford 

 not only protection but food to the trees. We would remove this cov- 

 ering as soon as it could be safely done in spring, to allow the ground 

 to receive the warmth of the sun, for nothing can be more injurious to 

 a tree, or any other plant, than to stand long with its roots in a soil 

 whose temperature is much below that of the air. The buds will cer- 

 tainly be excited into growth, and will make a draft on the roots for a 

 supply of sap, which the latter will be unable to afford. 



As soon as the ground is in condition to work, a dressing of good 

 manure or compost should be forked in lightly around it, more or less 

 in quantity as the condition of the soil may require. If covered with 

 manure during winter, of course less will be needed than if little has 

 been used. Before the droughts of summer begin the covering should 

 be replaced, to sei've as a mulch during the hot weather ; and for this 

 purpose we would prefer litter to manure, which might have the effect 

 to excite a late growth in autumn, thus rendering the tree more liable 

 to injury during the succeeding winter. 



CANNA BIHORELLI. 



By David M. Balch, Salem, Mass. 



Canfia Bihorelli^ as is well known, differs from most other Cannas, 

 in its habit of flowering freely ; the stem branching repeatedly above the 

 uppermost leaf, and producing clusters of buds in long succession. In 

 favorable conditions, the floriferous capabilities of this variety seem 

 almost unlimited. About the middle of October last, I lifted a couple 

 of plants with several shoots, most of which had flowered through the 

 autumn, but two or three were half grown, and planted out in the 

 border of a warm green-house. To my surprise these have gone on 

 forming fresh clusters of buds and flowers, without cessation up to the 

 present time. No new shoots have appeared from the stool, but the 

 old flowering stems have divided and subdivided in the most curious 

 manner.
