circles of wood on the outside. Two years previously, the frost or winter had been sufficient 

 to kill the wood, hut not the bark, or perhaps portions of the wood contiguous to the bark, 

 and through this channel just enough sap had been drawn barely to support existence and 

 to send down two weak courses of wood. The conclusion was, that the bark of plants pos- 

 sesses sometimes a greater power of resisting the effects of frost than their wood. The short 

 supply of sap produced by these circumstances caused the yellowness in the leaves. 



Repeated examinations of a peach-tree under the "yellows," since the case above stated, 

 show that the peach also will carry its bark safely through a winter severe enough to destroy 

 the wood which it encloses, and that the same reduced supply of sap produces the same 

 identical "yellows" as in the Evonymus. 



Supposing this view sound, what cure would it point out for the " yellows ?" None. It is 

 incurable ; the wood is diseased — dead — cannot be renovated ; but preventives are very appa- 

 rent. Always plant in warm soil, and if the atmosphere of the locality is any way humid, 

 choose an aspect not freely exposed to the winter's sun ; or if there be any causes leading 

 to late growths or succulency that cannot be removed by aspect, much might be done to- 

 wards the early ripening of the wood by divesting them only of their foliage. The two 

 main preventives are — first, early ripening of the wood ; second, by guarding against bursts 

 of hot sun on thoroughly frozen wood, the chief cause of much injury frost has to account 

 for. — Melocoton, {Philadelphia Florist.) 



Strawberry Culture. 



A correspondent of the Gardener's Chronicle (England) calls attention to the following 

 new facts connected with the cultivation of the strawberry ; he says — 



The first year's produce of strawberry-plants from runners of the preceding season is 

 generally considered of little account ; but, with attention to certain points of treatment, I 

 have reason to believe that it may be made nearly equal to the average produce of the second 

 year. I observed lately, in the grounds of a market-gardener, a bed of Keen's seedlings, 

 which, he informed me, were from runners of last year planted out at the end of summer. 

 They were bearing plentifully, though perhaps not carrying so heavy a crop as a neighboring 

 bed two years old ; nor were the plants, of course, so large and stocky. I have myself some 

 plants of another kind, from runners of last year, which have six and eight fruit-stems or 

 trusses ; and the aggregate amount of fruit borne on these plants is quite equal to that on 

 any of the plants from which they were made, now two years old. The course I adopted in 

 making these plants was this : In June, last year, I laid down such runners as I wished to 

 make fresh plants from, removing all others as they were thrown out, whether from the 

 parent plants or from the rooted runners. In September, the now rooted plants were de- 

 tached from the old ones, and removed with a ball of earth to the place where they have 

 since remained. The removal might, I presume, be as advantageously made at a later period 

 — say in October or November — if the ground they are intended to be placed in should hap- 

 pen to be occupied at an earlier time with other crops. By paying attention to laying down 

 a limited number of runners early, and concentrating the energies of the parent plant in 

 causing them to form their roots, I consider that the constitutional maturity and bearing 

 power of the new plants are materially forwarded, so as to enable them to produce a fair 

 crop the next season, instead of having the ground almost uselessly occupied for a whole 

 year with immature and imperfectly-bearing plants, as must necessarily be the case when 

 the beds are made in spring. 



Strawberries of 1855. 



M. P. Barry, of Rochester, New York, communicates to the Horticulturist the following 

 results of his experience with some of the more recent varieties of strawberries during the 

 past season : — 



Scott's seedling, of which we had but a very small bed, and consequently a trial not quite 

 satisfactory, has not come fully up to its Boston reputation. It is large and handsome, and
