Method of destroymg the Mealy Bug. 225 



-well known, that the outsides bear more abundantly than the 

 insides, and if only two rows here, and two more in another 

 place, I have four outsides ; whereas, were they all sown to- 

 gether, I should have but two outsides. Besides, two rows in 

 one place occupies 3 ft. 6 in., and two rows in another the 

 same, making together 7 ft. : but were four rows sown to- 

 gether, they would take up 11 or 12 ft. of ground. 



If you think these remarks worthy a place in your excellent 

 publication, they are at your service.

Art. XVI. Method, of destroying the Mealy Bug, and a De- 

 scription of a Portable Vinery. By Mr. James Rollins, 

 Dingle Bank, Liverpool. 



Sir, 



I AM surprised, and even sorry, to see so few communica- 

 tions from this neighbourhood in the pages of your Magazine; 

 there are many things and practices hereabout which deserve 

 to be recorded, and I regret that I am incompetent to the 

 task myself, and very much wish I could induce some abler 

 pen to convey to you such reports as would be worthy of a 

 place in your work. 



I venture, however, to present you with an effectual remedy 

 for freeing the Amarj'lli^ family of plants from the mealy bug 

 which sometimes so much infests them. Dissolve one dram 

 of mercurial ointment in 1 oz. neat's-foot oil ; with this mix- 

 ture anoint the infected plants with a small painter's brush, 

 allowing some of it to pass to the bottom of the leaves, and in 

 among the scales of the bulb; and this, when thoroughly done, 

 will kill or banish the insects for ever, without at all hurtins: 

 the plant. 



I also beg to mention an idea of mine, which may be useful 

 to those who happen to have no hot-house. In order to have 

 a crop of well-ripened grapes in the open garden, without 

 the expense of building a house for the purpose, I would re- 

 commend a glazed frame, constructed of the cheapest ma- 

 terials, which I would call a portable vinery. It may be 

 made circular, or a polygon of any number of sides; about 

 3 ft. 6. in. diameter, sides 4 ft. 6 in. high, and a roof finished off 

 like that of a common hand-glass. Any vine which happens 

 to be growing on a south wall, or even a suitable branch of 

 such a tree, may be taken from the wall, and trained spirally 

 round a conical trellis fixed to the ground, and of no greater
