1. Account of a Mode of managing Peach Trees in an early Peach- 

 house. By Mr. Walter Henderson.. C.M.H.S., Gardener to 

 Walter Frederick Campbell, Esq. M.P., at Woodhall, Lanark- 

 shire. 



This paper describes a very successful method of training 

 and managing peach trees, which the writer says he has fol- 

 lowed for 27 years. The forcing-house is 45 ft. long, and 13 ft. 

 6 in. wide ; the height of the front is 4 ft. 6 in. The trees 

 are planted within the house, at the distance of 3^ ft. from the 

 front glass, and trained up a perpendicular trellis, till within 

 2 ft. 3 in. of the roof sashes, at which point the trellis is carried 

 parallel to the roof, all the way to the top. There is only one 

 flue, which, coming from the back at the east end, runs along 

 the border to the opposite end of the house, returns, and enters 

 a chimney over the fireplace. Between the flue and the back 

 wall, there is a pit filled with leaves, which, during ferment- 

 ation, throws up a steam, which is considered beneficial to the 

 health of the trees. The house is generally shut up about the 

 1st of December; but no fire is made for a fortnight, unless 

 the weather is frosty, and then only on nights. In a month 

 the buds begin to swell, and then the strongest are easily dis- 

 cernible ; the shoots bearing them are retained, and the greater 

 part of the remaining wood which bore last year, and all weak 

 shoots, are cut away ; and the others tied to the trellis, at dis- 

 tances of about from 6 in. to 9 in. apart. These shoots, during 

 the summer, are not kept tied to the trellis, but suffered to 

 rise upright towards the glass, where, from being regularly
