as possible, and plunging them in any convenient spot in any 

 forcing-house at work ; shading them, and giving them plenty of 

 water. Should there not be a forcing-house at work, it will not 

 require much dung to force a small quantity in a frame in the 

 same manner as asparagus ; or in a vault made under a cucumber 

 frame, as prescribed by Mr. Smith in his Treatise on the Cucum- 

 her and Melon, which, if followed up, will succeed admirably, 

 either with or without the asparagus frame. When none of 

 these conveniences can be had, it will succeed in a warm cellar, 

 or in any other spare house where the temperature is a little 

 above that of the open air. To those who prefer the flavour 

 of green rhubarb, the addition of a little acid juice or lemon 

 peel will answer the purpose.

Transactions of the Pennsylvania Horticultural Society. 8vo. Philadelphia, 

 1839 and 1840. 



This Society was founded in 1828, and it appears to be one of the most 

 prosperous in America. The list of plants exhibited is not inferior in point 

 of number and variety to those of many of the provincial societies of England, 

 and the culinary vegetables and fruits shown are in greater variety than what 

 usually takes place with us. The number of forced articles exhibited is as- 

 tonishing, considering that fifteen years ago, as we have been informed, there 

 was not that number of forcing-houses in all the United States. The library 

 of the Society contains 300 volumes ; and the Society intends to establish a 

 garden as soon as the funds will admit. 



Book of Fruits ; being a descriptive Catalogue of the most valuable Varieties of 

 the Pear, Apple, Peach, Plum, and Cherry, for the Neiu-England Cidture. 

 By Robert Manning. To which are added the Gooseberry, Currant, Rasp- 

 berry, Strawberry, and the Grape ; with Modes of Culture ; also Hardy 

 Ornamental Trees and Shrubs. With plates. First Series for 1838. 12mo, 

 pp. 120. Salem, 1838. 



The Pomological Garden at Salem, we are informed by Mr. Manning, con- 

 tains 1500 vai'ieties of hardy fruit trees, and additions are made to it every 

 year from the best fruits of America and Europe. No scions are given out 

 until the fruit is proved, and till a reference can be given to some authority by 

 whom, or in which, it is described. Among the directions for planting we 

 find spring is preferred to autumn, and that " trees should rarely be placed 

 deeper in the ground than they originally stood in the nursery." A very 

 useful hint to an American planter, as would appear from Mr. Bridgeman's 

 remarks on this subject, quoted in our preceding volume.
