with boarded shutters. Mr. Holford says, if ventilation, is 

 required in severe weather, it can be effected by metallic pipes ; 

 but there are always fine days enough to admit of opening the 

 sashes for this purpose.

 Letter to the Secretary. By Mr. George Mugliston of Repton,

An ingenious plan, but not calculated to be effective on a 

 large scale, without occupying too much room. Mr. Kew- 

 ley's plan (Encyc. of Gard. 1490) or one which we have heard 

 Mr. Sylvester describe, would, in our opinion, be greatly su- 

 perior, as they would operate directly on the common sashes 

 of any hothouse. In the case of iron-roofed houses, liable to 

 be suddenly elevated in temperature, by sudden gleams of 

 sunshine, and depressed by clouds, or wind, a good contriv- 

 ance of this sort might be advantageously introduced.

Woollen nets, or a patent imitation of netting, having the 

 meshes sufficiently wide to admit the ingress of bees, is the 

 best material ; but " I employ and recommend small branches 

 of two feet in length, of the birch tree, collected as soon as 

 the leaves have become full grown in the end of June, and 

 preserved till the following spring." Secure them by a few 

 nails and shreds, with their points hanging perpendicularly 

 downwards. When danger is over, take them away in small 

 quantities at a time. 



79. On the Cultivation of Asparagus, during the Winter. By 

 Mr. Peter Lindegaard, Gardener to His Majesty the King of 

 Denmark, at the Royal Gardens of Rosenburgh, Corresponding 

 Member of the Horticultural Society. Read May 4, 1824. 



My chief crop is always delivered on the king of Den- 

 mark's birth-day, January 28th, and forcing is consequently 

 commenced four or five weeks before that date. Stir up the 

 beds in the open garden with a fork, and heighten them with 

 a spit taken from the alleys, which are two feet wide ; the beds 

 are four feet wide, and there are two rows on each bed ; deepen 

 the alleys to three and a half feet, then fill them with hot 

 dung, and cover the beds with litter. One plank over the 

 alley and another along the centre of the bed, between the 

 two rows, will enable a man to walk and gather the crop, 

 without injuring any thing.
