intended for, must be made with a loop at one end (f), to place 

 over the iron d; the other end must be fitted with a thumb- 

 screw (<?), to screw up the wire when it is placed in the notch g, 

 which should be counter-sunk in the centre. Small hooks should 

 be driven in the frames, either front or back, to lay the wires in 

 when not in use. The irons for the middle wire may be put on 

 so that it may be screwed at the opposite end to the other two. 

 It may be proper to add that the mode of fastening on mats 

 is the invention of Mr. Smith, my predecessor, and the present 

 steward. — JRosehill, Sussex, Jan. 1842. 



Art. X. Notice of some Ornamental Trees and Shrubs recently sent 

 to Britain by Messrs. Booth of Hamburg. By John Booth. 



[Having written to Messrs. Booth for some account of the J'cer colchicum, 

 for the Supplement to the Abridgement of our Arboretum Britannicum, they 

 kindly sent us what follows.] 



A^CER colchicum, named thus by Hartwiss, is indigenous to the 

 Abchasian country, which lies between lat. 42° 30' and 44° 45' N., 

 and between long. 37° 3' and 40° 36' e. The bark, particularly 

 of the young shoots, has a greenish colour, resembling in this 

 respect that of the JVeg/m^/raxinifolia, while the leaf resembles 

 that of the Acer LobehV. Hartwiss and Steven are decided in 

 considering it a distinct species. Along with this species I im- 

 ported a variety of it, which I have named 



A y cer colchicum var. rubrum Booth. In point of appearance, 

 this is the more desirable tree of the two. From the beginning 

 of the season till late in autumn, the leaves are of a bright 

 pinkish purple colour, and the bark is brownish. The first 

 plants that were sent to Europe I received from Professor Hart- 

 wiss. Both the species and the variety have here proved hardy. 

 Plants in our arboretum, exposed and unprotected during the 

 winter of 1840-41, sustained no injury whatever.
