P.S. We have since received from Mr. Andrews a sketch of 

 a summer-house or grotto, which he has lately erected in the 

 garden of Mr. Low of Edmonton. " It is," says Mr. Andrews, 

 "of an octagonal form. The lower part is composed of burs, flints, 

 shells, &c. ; and the upper part is divided into Gothic compart- 

 ments, formed of ash hooping with the bark on, cut into short 

 pieces, and bradded upon deal boards well tarred; the Gothic 

 arches are covered with the same material, which has a very 

 pretty effect. The roof is put on square, as thatching does not 

 look well, unless the angles are acute. The porchway, com- 

 posed of vergeboard pendants and shells, is supported upon 

 four pillars of spruce fir with the bark on, and is brought out 

 far enough to allow the door to open within it. On the side 

 opposite to the door, are two windows. A fan-like madrepore 

 is placed on the upper part of the porch ; and the inside of the 

 grotto, above the seats, is covered with shells, spars, corals, ma- 

 drepores, moss, &c." We have inserted this notice, chiefly for 

 the sake of making known that Mr. Andrews is a garden artist 

 in the department of rockwork, fountains, summer-houses, &c.

No. 14. Apple Insects. 



The almost total destruction of the apple crop in the chief 

 cider counties, during the present season, has naturally caused 

 attention to be directed to the cause of the failure, with the view 

 to the discovery, if practicable, of the precise circumstances 

 in which it has originated, and of remedies for its prevention in 

 future seasons. It would lead me into a very wide field, to at- 

 tempt to prove the importance of this fruit in the domestic 

 economy of our island. Much interesting matter relative to the 

 cider manufactory has been collected in the Arboretum Britan- 

 nicum ; but I have not yet met with what may be termed the 

 statistics of this branch of our national resources, of which a 

 sketch would, I have no doubt, show that it far exceeds the or- 

 dinary notions entertained respecting it ; moreover, as the ex- 

 portation of cider is carried on to a considerable extent, it must 

 be evident that the failure of the apple crop must have an ejffect, 

 not, indeed, comparable with that of the hop crop, but still very 

 prejudicial both to the grower and the revenue.
