14 Progress of Horticulture for 1852. 



ing up every year, as in the old mode of glazing. We have 

 long recommended this system to all our friends who are 

 constructing greenhouses. One of our houses is a curvilinear 

 one, but not an atom of putty was made use of, only to bed 

 in the glass. 



Commercial Gardening. 



The season just closed has been one of greater activity 

 with nurserymen than usual. A healthier state of the mon- 

 etary affairs of the country has enabled purchasers to buy 

 more liberally than the two previous years. In addition to 

 this, a new market has been opened by the demand for trees 

 in California. This has taken off the surplus stock of the 

 larger nurseries in the Middle and Eastern States, and given 

 additional impulse to the business everywhere. No doubt 

 the abundant wealth of California will continue for some 

 time, coupled with the fineness of the climate for the pro- 

 duction of fruits, to require large quantities of trees, which 

 for the present, must be supplied from the States. 



Horticultural Literature. 



But few works have been published the past year. These 

 are Country Houses, by the late Mr. Downing ; Walks and 

 Talks of an Atnerican Farmer, by Mr, Olmstead, forming 2 

 vols, of Putnam's Library ; Rural AgrirAilture, by L. F. 

 Allen ,• and 2 numbers of the Fruits of America, Yol. IL 

 New editions have appeared of the Fruits of Amei'ica, Breck's 

 Book of Flowers, and Thomas's Fruit Culturist. Quite a 

 change has taken place in the periodical press. The Horti- 

 culturist will hereafter be published at Rochester, edited by 

 P. Barry. The Cultivator is reduced to 50 cents a year ; 

 and Mr. Tucker starts a new paper, called the Country Gen- 

 tleman. The Plough gives way to the New York Agriciil- 

 tor, (weekly,) and the Fartn and Garden, (monthly.) The 

 American Gardeners^ Chronicle is to appear weekly, at ^2 

 a year ; and the Philadelphia Florist is to be augmented 

 in size and improved in appearance, at f 2 a year.
