because it discourages the existence of insects, and destroys 

 their ova, but it likewise facilitates the setting and swelling of 

 the fruit. I ought to observe, that I am not offering any 

 opinion of my own in the present statement, but merely re- 

 cording, as faithfully as possible, the remarks made to me by 

 a person of ingenuity and observation, whose extraordinary 

 success is, in my mind, the best test that can be given of the 

 merits of his practice. 



The trees are planted in a bed of rich mould, represented 

 in Figure L of the section ; the roots are at liberty to extend 

 horizontally underneath the plate which supports the front 

 sashes, to the outside of the house as far as the extremity of 

 the bed, but are restricted from pushing downwards by 

 means of a layer of broken tiles rammed down underneath 

 the bed of compost. 



The vinery is 54 feet long and 12 feet wide, very rudely con- 

 structed by one of the workmen on the farm, who was not bred

 to slide, the only means of giving air being the doors, and 

 flaps of deal board which run along the top, the whole length 

 of the house, as represented in figure G. These are thrown 

 open, by means of swan-neck hinges on the upper side, fixed 

 on the coping plate of the wall ; this Mr. French considers 

 an excellent method of allowing air to escape from the top 

 of the house, where the hottest must accumulate, and the 

 top being divided into convenient lengths, an option is re- 

 served of giving much or little vent, as circumstances require. 

 I observed many orifices and crevices between the sashes 

 and door frames, through which air must find a passage
