of repairs being required in the lapse of time, and I 

 believe the expense was not one-third of what a stone 

 bridge would have cost, although plenty of stone is 

 to be found on the spot. 



Besides bridges for carriages, Mr. Justice has erect- 

 ed a number of foot bridges, some of which are up- 

 wards of sixty feet span, and which did not cost more 

 than L.40, including mason work ; and these not on- 

 ly carry as many people as can go on them at once, 

 but as many horses. Bridges of the same span, for 

 carriages, will cost more, independent of mason 

 work. These bridges are adapted to every situa- 

 tion, but some situations will cost much less than 

 others. 



I may also observe, that in wooded dens and ra- 

 vines, where there is rock on both sides, which is of- 

 ten the case, these bridges could be erected at an ex- 

 pense of little more than twenty shillings for mason 

 work, and put up by an ordinary mechanic, as they 

 are all put together and proven at the factory.

The following plantations, though the names of 

 the estate, or particular spot where they grow, is not 

 given, yet they are so particularly described, and the 

 method of planting, draining, thinning, pruning, and 

 rearing, is so minutely entered into, that no forester 

 or rearer of woods will be at any loss at once to dis- 

 cover a proper method of recovery and improvement 

 for every corresponding wood or plantation under 

 their management, on any estate in Great Britain or 

 Ireland.
