 There is no doubt upon my mind, that 

 if the soil be well drained, and not too 

 fertile, blistering will never occur. The 

 remedy, therefore, is obvious in eitlier 

 case.

 Dew, Mildew, Exlravasated Sap. 



Forcing. Any of the early varieties 

 are suitable for this purpose ; success 

 does not depend so much on the kind, 

 as on the manacement. 



Form of House. — The best form for a 

 Peach-house, is that thus described by 

 the late T. E. Knight, Esq. 



As the lights to be moved to the re- 

 quired extent with facility must neces- 

 sarily be short, the back wall of the 

 house must scarcely extend nine feet 

 in height, and this height raises the 

 rafters sufficiently high to permit the 

 tallest person to walk with perfect con- 

 venience under them. The lights are 

 divided in the middle at the point a, 

 and the lower are made to slide down 

 to the D, and the upper to the point a. 

 The iiue, or hot-water pipe enters on 

 the east or west end, as most conveni 



line c, will receive the full influence of 

 the sun. The upper lights must be 

 moved as usual by cords and pulleys, 

 and if these be let down to the point a, 

 after the fruit in the front tree is gather- 

 ed, every part of the trees on the back 

 wall will be fully exposed to the sun, at 

 any period of the spring and summer 

 after the middle of April, without the 

 intervention of the glass. A single fire- 

 place will be sufficient for a house fifty 

 feet long, and I believe the foregoing 

 plan and dimensions will be found to 

 combine more advantage than can ever 

 be obtained in a higher or wider house. 

 Both the walls and flue must stand on 

 arches, to permit the roots of the trees 

 to extend themselves in every direction 

 beyond the limits of the walls, for what- 

 ever be the more remote causes of mil- 

 dew, the immediate cause generally 

 appears to be want of moisture or 

 dampness above it. A bar of wood 

 must extend from d to b, opposite the 

 middle of each lower light, to support 

 it when drawn down. — Knight's Select 

 Papers. 



The soil, culture, and pruning are 

 the same as required for those trees 

 grown on walls. 



Forcing in Pots is a very excellent 

 mode, and enables the Peach to be 

 thus grown in establishi:.ents where 

 there is no regular Peach-house. Pot a 

 three year old tree in a twelve inch pot, 

 cutting it back to four buds; and shift 

 every year until it has attained an 

 eighteen inch pot, a size which need 

 never be exceeded. Let the soil be 

 turfy, and mixed with decaying wood 

 from the bottom of an old wood 

 stock.

ent, and passes within six inches of the 



east and west wall, but not within less j The best and most successful directions 



than two feet of the low front wall, I on these points are the following, given 



and it returns in a horizontal direction 

 through the middle. The trees must 

 be planted between the flue and the 

 front wall, and the other row near the 

 back wall, against which they are to be 

 trained. 



If early varieties be planted in the 

 front, and the earliest where the flue 

 first enters, these being trained imme- 

 diately over the flue, and at a small dis- 

 tance above it, will ripen first; and if 

 the lower lights be drawn down in fine 

 weather to the point b, every part of

 Eatington Park. He says: — " Bring the 

 trees into the house in mild weather 

 during November, a little earlier or 

 later according to the state of the 

 weather; do not start them all, how- 

 ever, at once ; the last lot are not put 

 in until the first of January. Any later 

 than this would not answer, as the 

 weather, if clear, is then hot through 

 the day. Commence forcing them at 

 530 at night, allowing the thermometer 

 to fall to 50" in the morning, if cold, 

 but if the weather is mild, never to fall 

 below 55*-' ; and from thai to 60« is the
