ON HEATING PLANT STRUCTURES.

in its stead. The house is in an exposed situation, lias a slant roof, 

 with lights in front, measuring 42 by 13 feet in the clear. On 

 each side and at the bottom of the house is a stnking-pit, with slate 

 bottom, leaving a two-feet walk down the centre; the warm air passes 

 in large quantities under the pit, which forms a good bottom-heat, and 

 makes its escape into the house through ventilators at the sides in such 

 quantities as the gardener may require. Since its introduction we have 

 used this house for forcing flowers in winter, such as Roses, American 

 plants, Pinks, &c. &c., and can confidently state that we have never 

 had tliera so fine under any other mode of heating, more particularly 

 the Roses, which were exceedingly fine, many of the moss producing 

 from twenty to twenty-five flowers on each plant. When the forcing 

 season is over, we then fill the house mostly witli Amaryllis, to give 

 them their summer's growth. Amongst these we place specimen stove 

 plants, such as Allamanda, Dipladenia, Ixora, Bayetta, Clerodendron 

 Turnera, Inga, &c., all of which flourish and produce abundance ot 

 flowers, far finer than in our houses heated on the old principle of 

 steam, fire-flues, &c. We also find some orcliids much improved since 

 they were removed into this house, especially Cattleyas, of which we 

 have now a handsome specimen in C. intermedia, in fine bloom, and 

 which has been so for the last six weeks. We have always been 

 enabled to keep the house at a uniform temperature from 60^ to 7o , 

 and the fire requires attendance merely night and morning ; the cost 

 of fuel does not exceed three-pence per day. Such is our good opinion 

 of this system over all others, that we wish the whole of our liouses 

 were heated as this experimental one is. We shall be happy to show 

 it to any one who may wish to inspect it.

" Church Warming on Hazard's PKiNCirLE. 



" It may be interesting to your readers to have the following^ ac- 

 count of an attempt to warm a church on Mr. Hazard's plan. The 

 experiment has been in every particular so entirely successful— the 

 orio-inal cost, comnared with that of hot-water heating, so small— and 

 the^consumption of fuel so trifling, that I think it but fair to Mr. Hazard 

 to endeavour to call public attention to the great merits of his inven- 

 tion The church here is about one hundred feet by fifty feet, in the 

 widest part, and twenty-five feet higli, consisting of a nave, north and 

 south aisles, and chancel ; it used to be very cold and very damp. 1 he 

 construction of the church has given great facilities for erecting tlie 

 apparatus witiiout producing any disfigurement: outside there is 

 nothiixr visible, except from one point ; and, inside, all that appears 

 are the° "rates in the face of the walls through which the heated air is 

 poured bito the church. There are five of these ; one in the north 

 aisle one in the nave, two in tlie chancel, and one in tlie vestry. Some 

 parts of the churcli are distant from fifty to sixty feet from tlie nearest 

 grate. The apparatus is one of moderate size ; four rows ot hve pipes,
