J 6 Effect °f the Lombardy Poplar. 



rotten, collapse, and either fill the cavity described to exist at 

 the bottom of the stalk of the fruit, with a preternatural col- 

 lection of putrid water, which quickly causes the stalk to decay 

 at its base, and, consequently, the young fruit to fall off long 

 before it even approaches maturity, or which, when the re- 

 mains of the flower become pendulous, keeps the young fruit 

 and its support so damp as to produce the same effects. But 

 if, with a pair of very sharp scissors, the whole of the fleshy rays 

 are remooved after the flower is fecundated, all this inconveni- 

 ence is avoided, and, in most cases, the fruit will swell and 

 arrive at maturity, especially if a little pollen be applied to the 

 stigmas, with a feather or a bit of any soft substance. 



This is a very simple contrivance, and it would seem obvious 

 enough ; but the cause of the failure in obtaining fruit being 

 generally unknown, it is not surprising that the mode of re- 

 moving the impediments to its maturation should have been 

 also overlooked. 



The figure, at the end of this communication, will serve to 

 explain the peculiar structure which I have attempted to point 

 out. 



Those who may desire to find a detailed account of the various 

 kinds of granadillas, will do well to consult the Horticultural 

 Society's Transactions, vol. iiL p. 99., where there is an ex- 

 cellent account of them, by Joseph Sabine, Esq., the Secretary. 



Art. III. Remarks on the Effect of the Lombardy Poplar in 

 Park Scenery. By Mr. John Thompson, Landsurveyor 

 and Pictorial Draughtsman. 



The Lombardy poplar is a tree, which, as applied to the 

 science of arboriculture, is capable of producing not only the 

 most noble and striking, but the greatest variety of effect ; and
