tempts were not succefsful j the exact variation that was re- 

 quired on the machinery, could not at once be preciseljf 

 ascertained. Succefsive trials, however, at last brought 

 about the discovery. Many machines for carding and 

 spinning wool have been erected in England, and some ia 

 Scotland, which have been found to succeed extremely 

 well. This branch of manufacture is, however, still in its in- • 

 fancy, and we only here note it to marli the progrefs of im- 

 provements. One machine has been erected at Dundee, for 

 coarse w^ool chiefly. Another has been just set agoing at 

 Edinburgh, for the finest kinds of wool, which performs 

 its operations with amazing delicacy and accuracy ; so that 

 there seems to be no room to doubt, that our fine woollen . 

 fabrics will be very much improved by that circumstance, 

 the price of goods thereby diminiflied, and the extent of / 

 sale of course proportionally augmented. Both these ma- 

 chines are on a small scale, and being establifliedin places 

 where running water cannot be had, as a moving power, 

 they can be considered only as experimental efsays. 

 Linen yarn spun by machinery. 

 This is a farther extension of Mr Arkwright's discove- - 

 rlcs. It was long doubted whether it would be pofsible- 

 to get llax spun by machinery ; — the succefs of several 

 trials both in Scotland and England, have fully establilhed 

 its practicability. Some time ago a machine was erected 

 in the neighbourhood of Dundee for spinning coarse tow, 

 (the ihort stuff that qomes from flax in the drefsing) which 

 has been found to answer extremely well. Another mill 

 has been erected near Leven. in Fife, for spinning fine 

 flax. This is an improvement on the original machine c- 

 rected at- Darlington in England, which was not found 

 to answer at first the expectations of the undertakers. That 

 at Levep, we are afsured, makes yarn of such an excellent
