THE GARDENER'S MONTHLY 



[October, 



rapid growing trees with great profit. Many 

 young trees of Ash, Maple, Hickory, &c., could 

 be taken up by farmers, planted for a couple of 

 years in nursery rows where they could be culti- 

 vated, and then transplanted to broken ground 

 and hillsides, with great certainty of living. 



QUERIES. 



^' Fall-Planting Larch. — M., Amherst, Mass., 

 writes : "Will you have the kindness to inform 

 me'if you have ever practiced fall planting of the 



European Larch. We have a lot of seedlings 

 that we are thinking of transplanting for forest 

 growth and 'fall planting would save us much 

 expense.' " 



[We should not recommend fall-planting 

 young Larches, because the frost would probably 

 draw out such small things ; but young Larches 

 ought to be drawn out in the fall, and bedded in 

 thickly where they can be got at early in the 

 spring. This keeps back their early growth 

 somewhat, and enables one to have time to plant 

 large quantities before the leaves push. —

COMMUNICA TIONS. 



THE APPLE LEAF FUNCUS-Roestelia 

 cancellata. 



BY PROF. W. A. BDCKHOUT, STATE COLLEGE, CENTRE 



COUNTY, PENNA. 



The September number of the Gardener's 

 Monthly contains a notice of the Annual Meet- 

 ing of the Georgia State Horticultural Society, 

 and upon the subject of the relation of the apple 

 leaf fungus to that producing "cedar apples," 

 you remark that "Unfortunately, little is known 

 of the manner in which Roestelia works, so that 

 no one can suggest any remedy. The fungus 

 which makes the 'apple' on the Cedar is the 

 Podisoma, and has no relation to the Roestelia " 



That Roestelia and Podisoma are but two 

 stages of one fungus has been the opinion of 

 those who have carefully studied them in both 

 the laboratory and orchard. In proof of the 

 former, I beg leave to refer to the proceedings of 

 the Danish Academy of Sciences, an abstract of 

 which is given in the American Naturalist,Yo\. II, 

 page 557, and to Sach's Botany, page 246. The 

 most recent of our botanical works, Bissey's and 

 Plant's, state unhesitatingly, the general accept- 

 ance of this matter of "heteroecism" among the 

 fungi. 



Of cases coming to the notice of orchardists, 

 that which I communicated to the February 

 number of the American Agriculturist (1880), and 

 is referred to in this meeting of the Georgia 

 Horticultural Society, is the best, though not the 

 only one, of which I have knowledge. In this 

 instance the attack upon the fruit as well as the 



leaf was very marked, and shows a danger, which 

 under circumstances specially favorable to the 

 development of fungi, may prove very great. 



I believe we know enough of the nature of 

 Roestelia, and the manner in which it works to 

 suggest as a remedy, the destruction of all Cedar 

 trees which have become infested with " Cedar 

 Apples," especially when they are in the imme- 

 diate neighborhoo 1 of orchards. 



THE CLINC-STONE APRICOT. 



BY MISS JOSEPHINE K. KLIPPART, COLUMBUS, OHIO. 



In answer to the article in the September 

 number on the " Change of Character in a Fruit 

 Tree," I will say that I most assuredly do mean 

 that the tree in question is an Apricot and not a 

 Peach at all. The leaves and fruit are not to be 

 mistaken in the least degree for the Peach. I 

 have been " brought up " on Apricots and know 

 whereof I speak. During State Fair week we 

 entertain many friends, and this year Dr. Warder 

 and N. Ohmer — well known Ohio pomologists — 

 were our visitors for a short time. Dr. Warder did 

 not see the tree. N. Ohmer examined the tree, 

 and said that the reason of the fruit changing to 

 clings was undoubtedly the old age of the tree. 

 Another gentleman present was quite as decided 

 that it was the impoverished condition of the 

 soil and the borers. 



The top of the tree is covered with an abund- 

 ance of healthy green leaves, and no dead twigs 

 are to be seen. The last gentleman who examined 

 it advised us to give it a good top dressing, and 

 throw up a bank of ashes and a little salt around
