snow which falls on the summit of the tree in 

 severe winters, and if they give way in any 

 place the boughs are frequently broken. In the 

 arboretum which the late Joseph Strutt, Esq. 

 most liberally presented to the town of Derby, 

 there is a very fine weeping ash, for which Mr. 

 Strutt had an iron framework made. The iron 

 rods are light and elegant, and vet so strong; 

 that they are in no danger of giving way under 

 any weight of snow that is ever likely to fall on 

 the tree. The iron framework has been coated 

 over with gas tar, to preserve it from rust, and 

 it looks exceedingly well. 



Roses. — These beautiful shrubs are so gene- 

 rally admired, and they are grown so universally 

 in all gardens, that I think I ought to give some 

 especial directions for their culture. In the 

 first place, roses are said to require removing 

 every third year; as they rapidly exhaust the 

 soil, and their fibrous roots are few, small, and 

 not widely extended from the bole of the plant. 

 It is not, perhaps, necessary to take this rule 

 strictly au pied de la left re, but it is as well to 

 keep it in view, and to remember that when 

 rose trees look sickly, or fail to produce a due 

 proportion of flowers, removing them to a fresh 

 soil will, in most cases, restore their vigour. 



It is not, perhaps, generally known, that there 

 are nearly two thousand species and varieties of 

 roses. Among such a chaos it would be almost 

 impossible to choose, had not florists arranged 

 them in about twenty general divisions. One 

 of the principal of these contains the Cabbage 

 Roses, and their beautiful descendants the Moss 

 Roses ; of which last there are more than twenty
