tween which and the trees the plough and 

 cultivator were used, were more than twice 

 as large as those in any other row. This 

 result convinced me fully of the great im- 

 portance of frequent, thorough, and deep 

 cultivation. 



The second year, (1847,) I planted the 

 ground on which the beets and carrots grew, 

 to corn, leaving an open space about each 

 tree equal to eight hills of corn, which I 

 planted to potatoes. The trees did tolera- 

 bly well, but did not grow more than those 

 in the nursery grew the first year. This 

 year, 1848, I sowed to oats the same corn 

 graund, keeping a spot about three feet in 

 diameter hoed about each tree till the oats 

 came ofT; this year the trees grew less than 

 last, and are not now much larger than 

 those in the nursery ground were at the 

 end of one year from the time of plant- 

 ing. 



The orchard trees planted on the nursery 

 ground have grown very rapidly, and pro- 

 duced, this autumn, about thirty or forty 

 bushels choice peaches ; and the nursery 

 trees have grown well. I may also remark, 

 respecting the nursery peach trees, that in 

 taking them up (and I have taken up more 

 than 25,000 of them,) I think that not one 

 in a hundred appear to have been touched 



by the peach worm, while, on similar land 

 in this immediate vicinity, to which ashes 

 has not been applied, a very large portion 

 of young peach trees are very much in- 

 jured, and many entirely destroyed by the 

 worm. 



My orchard peach trees on that ground 

 have also entirely escaped the worm, while, 

 on other parts of my ground, my trees are 

 much injured by them. 



A portion of the 15 acres enriched with 

 muck and ashes, was sowed to barley in 

 1846, and produced a large crop. It was 

 again sowed to wheat in the fall of 1846, 

 and produced 30 bushels per acre. This 

 year, 1848, 1 planted four acres of the wheat 

 ground, to corn ; about one acre of which 

 was ploughed last fall with a subsoil plough, 

 and the four acres yielded, on an average, 

 179 bushels of ears of sound corn per acre. 

 That part which had been subsoiled was 

 considerably the best. 



The peaches grown on my trees in my 

 nursery grounds, among the small trees, 

 were about a week later in ripening than 

 the same varieties in my garden, where the 

 ground was more fully exposed to the sun. 

 Respectfully,

PEAR BLIGHT. 



BY J. W. BISSELL, ROCHESTER, N. Y. 



It is much easier to doubt the opinions or 

 reasons of others, than to give better ; it 

 is easier to say that the pear blight, known 

 here as the fire-blight, is not caused by 

 frozen sap, than to give the cause. 



This blight has been very destructive 

 the past summer, in some sections of this 

 city and vicinity, while others have entirely 



escaped. Scarcely any trees lying north 

 of a line parallel with the main street of 

 the city, and about half of a mile distant 

 therefrom, have been attacked this year, 

 while south of that line, on all soils, it has 

 carried dismay to the hearts of many culti- 

 vators and amateurs. Several years since, 

 that district which is now exempt, was se-
