dcr kinds of trees. We remarked specimens of Pistacia 

 Terebinthus, of both sexes, the female now sliewing fruit. 

 P. Lentiscus likewise here appears. The jujube-tree 

 (Khamnus Zizyphus) was in flower ; but it seldom gives 

 fruit so far to the northward as this: the jujubes sold 

 in the Paris shops are from the south of France. The 

 caper-tree Capparis spinosa, when trained to the wall, 

 and protected by a paillasson or straw-screen during win- 

 ter, succeeds pretty well. The same may be said of the 

 carob-tree or St John's-bread, Ceratonia Siliqua. The 

 olive, however, is kept in a tub or pot, like the orange. 

 The fruit of the bottle-gourd, Cucurbita Lagenaria, made, 

 at this time, a fine appearance on the same wall. The 

 squirting cucumber, Momordica Elaterium, was now ripe, 

 and exploded upon being slightly touched. It springs up 

 as a weed in this garden, and indeed has become naturalized 

 in many waste places about Paris. 



Our attention was directed to some espalier chasselas 

 vines, in which it very evidently appeared, that the hori- 

 zontal and depressed branches had produced many more 

 bunches of grapes than those which were trained upright. 

 This is a remark which may be turned to advantage in our 

 vineries at home, especially where the vines arc trained on 

 arched trellises under the rafters, thus at the same time ad- 

 mitting sun-light to the branches trained to the back-wall ; 

 for, both on the arched trellises and on the back-wall, the 

 horizontal and depressed inclination can easily be given. 



In the nursery, M. Du Petit-Thouars seemed to attach 

 great interest to a large peach-espalier, that is, a wall, per- 

 haps 100 feet long, clothed with peach-trees. The wall 

 has an eastern aspect, and is about 12 or 13 feet high : The 

 trees, after having been cut over above the graft, have fill-
