106 Calls at Gardens and J^urseries. 



be in every collection of heaths. E'pacris grandiflora was also charm- 

 ing with numerous racemes of" its delicate flowers expanded. The 

 Eutaxia myrtifolia was full of buds, as was also the Briinia verticillata. 

 There are several species of the Diosma here, two or three of which 

 will bloom. The common treepfeony had a very large flower expanded. 

 Several handsome camellias were also blooming. Metrosideros sem- 

 perflorens was showing its spikes of buds: the different species of this 

 tfenus are not so often met with in our green-houses as they should be; 

 they are all beautiful, and flower at a season when there are not many 

 other kinds in bloom. Indeed, nearly all the Australian and New Hol- 

 land shrubs, which are peculiarly adapted to our green-house culture, 

 remain yet to be introduced. 



Mr. Winchester's, Franklin-street. — Since our notice of the erection 

 of Mr. Winchester's green-house, we have had the pleasure of seeing 

 it. It is a very neat structure, upwards of twenty-five feet long, and 

 about twelve in width: it is heated both with a flue and hot water; the 

 former running across the house, from one end, under the stage, against 

 the back wall, and into the chimney at the other end; the latter runs 

 from the boiler, at the back, to the front, and across to the other end, 

 mto the reservoir. The command of heat is more than suflicient. Mr. 

 Winchester informed us that he, at first, constructed his furnace with 

 only a chimney, outside of the green-house, intending to heat it by hot 

 •water alone. This he was induced to do by the advice of some persons, 

 who stated to him that the hot water pipes would be sufficient to answer 

 all the purposes of keeping out the frost; but he found it would not do 

 without a very large quantity of pipe. This it was not convenient to 

 bring into the house, from its peculiar form, and the furnace was rebuilt, 

 too^ether with the present flue. We have conversed with some cuhi- 

 rators who think, without having made a trial, that the common hot 

 water system, of four inch pipes, will heat a house without a flue; but 

 we are convinced, that, unless they run completely round the house, and, 

 we are doubtful, even with this quantity, they will not be adequate to 

 the demand of heat. Those who hold this opinion do so, because they 

 have read in English works on gardening, that this system is adopted 

 inthat country; yet they do not take into consideration the difference 

 of temperature in the climate. Rarely there does the thermometer 

 fall more than lO^* below the freezing point of Farenheit, while 

 with us it descends 30"^ below, frequently 40°, and sonjetimes 50°; 

 this makes a vast difference between the systems of heating green- 

 houses in that country and this. We have in view some remarks 

 upon the proper mode of constructing furnaces, and heating stoves, 

 green-houses, &,c., and hope at some future time to give them to our 

 readers, accompanied with several plans. 



We found here, already, a very pretty collection of plants; among 

 the rest we noticed ten or twelve varieties of camellias, including J?6sa 

 sinensis, althseseflora, EIphinst6ni«, &.c. which had each a flower expand- 

 ed. Some handsome plants of Erica arborea and mediterranea were in 

 full flower. A fine plant of ./Scacia longifolia Avas one mass of golden 

 blossoms; it is one of the most showy species. Amaryllis psittacina 

 was throwing up a flower stem. It gives us great pleasure to see such 

 a taste spring up in this city, and cannot but have a good effect upon 

 the progress of gardening. Mr. Winchester thought that he had built 

 largely,' but he has found that he might have made his house of greater 

 dimensions, and then be too limited in space to hold the plants which 

 it would be his desire, from his growin^r taste, to cultivate. 



Mr. Siveetser's, Camhridgeport. — The display of camellias here has 

 been fine, and some very "pretty varieties have opened. The plant 

 noentioned in our last as about flowering, called gigintea, did not open
