THE BLACK WALNUT. 



leaves are a darker shade of green than 

 the A.merican variety, smaller in size, 

 but are borne in greater profusion, 

 forming a dense shade. The outline of 

 the ti'ee is regular and conical ; it will 

 suit itself to any soil, and is especially 

 adapted to large lawns. 



Mulberry (Morns). — The only va- 

 riety of this tree I have succeeded in 

 growing is the Russian. It quckly 

 attains a good height, and stands the 

 climate well ; although the tips of the 

 young wood often suffer, this does not 

 check the tree's growth. I have tried 

 Downing's, but it is far too tender. I 

 -should not advise any one building too 

 much on the fruit to be obtained, but 

 as it grows rapidly from cuttings, and 

 the fruit varies considei-ably amongst 

 the seedlings, one may arise in the 

 multitude of those grown, which will 

 be valuable. Its easy propagation, 

 freedom from suckers, quick growth. 



hardy nature, and capacity for 

 standing the knife should, I 

 think, make it a very suitable 

 plant for hedges. 



Black Walnut and But- 

 ternut (Juglans Nigra and 

 Juglans CinereaJ are both 

 hardy, and make attractive 

 looking ti'ees, of good size. 

 They are both of quick growth, 

 besides which they have the 

 nuts, for pickling and eating, 

 to commend them. Their 

 feathery, fern-like foliage gives 

 them a striking appearance, 

 and no place of any size should 

 be without a few specimens 

 of each of these trees. 



THE CATALPA. 



Sir, — I am sorry to report 

 tbe same as last year " That I 

 am afraid it is too tender for 

 this climate." Last spring it 

 came out strong to within li 

 inches of the tip of the last 

 season's growth which was about 18 

 inches, but the frost on the 6th of May 

 cut it down, and this year it has again 

 sent up a shoot from the root about 22 

 inches and has seemed to be very vigor- 

 ous the rest of the season. It is fairly 

 protected and is in good ground with 

 good drainage. A. J. Collins, Listowel.

ACCLIMATION. 



BY D. W. BBADLE. 



The readers of the Canadian Hor- 

 ticulturist may remember the purport 

 of a very interesting article Vjy Mr. D. 

 Nicol, at page 85 of Volume IX. In 

 it he gives the residt of thirty-two years 

 of endeavor to acclimate many half- 

 hardy shrubs and fruit ti'ees. The con- 

 clusion at which he arrives is this, '• that 

 trying to make tender plants hardy is
