The Cut-leaved Weeping Birch is always desirable. 



The i/o;>e Chestnut is hardy upon heavy clay soil, but it has always winter 

 killed upon our light sands. 



The two Catalpas, C. speciosa and C. Ugnonioides, are about equally hardy. 

 Both suffer considerably, and appear to be unreliable. As Catalpa speciosa 

 has not been recognised as distinct from the older species until quite recently, 

 the leading distinctions between the two may be given: C, speciosa — tree 

 tall, a straight grower; leaves softly downy, inodorus; flowers two inches 

 across, nearly white, the lort^er lobe notched; pods stout and long [1^ inch 

 in circumference). C. bignonioides — tree lower, diffuse in growth; leaves 

 smooth, or nearly so, giving a disagreeable odor when touched; flowers 

 smaller, dingy, the lower lip entire; pods more slender, leas' Japan Hybrid 

 Catalpa is not hardy. 



The Cucumber tree, Magnolia accuminata, was injured nearly every winter 

 until eight or nine years old. It endured the last winter better, although 

 the highest shoots were killed. Others of the Magnolias, although not 

 hardy, are desirable for the great annual shoots which have a tropical 

 appearance. 



The Lomhardy Poplar is short lived in this climate. 



Yellow-wood, Cladrastis tinctoria, is always desirable; very beautiful when 

 it comes into flowering. 



The Bald Cypress, Taxodium distichum, suffered last winter for the first 

 time. 



The Ginkgo, GinTcgo (Salisburia) adiantifolia, is perfectly hardy.

No. 8.— WINTERING BEES. 



The importance of bee culture, as one of our national industries, is hardly 

 appreciated. According to our well demonstrated modern ])hilosophy, plants 

 pour out their nectar as a sort of free coffee or lunch, to attract bees and other 

 insects to a most important work in vegetable economy, the work of fertilization, 

 which largely depends upon insects, and without which full fruitage is impos-
