2^6 BRIBGE OF A NEW CONSTRUCTION. June 2 2, 



Pcjlfcrlpt. After this work fliall be publifhed, I can 

 communicate a model of a complete bridge, as alfo one for 

 a houfe to cxercife cavalry and infantry, four hundred feet 

 in length within, without pillars and columns, after this me- 

 thod, to whoever Ihall want it, for a fuitable price. 



InleUigence ref/je£iir!>r a fort of plaflcr for helping the growth 



of trees^for the dfcovery of which, the inventor, Mr. For- 



fyth, the king''s gardener at Kenfington, it to have a reward 



of 7.000 I. in confequence of a report made in Ins favour by 



the cornmi/Jioners of crown lands, to whom it was referred, 



in purfuance of an addrefs prcfcnted lajl feffion by the Houfe 



of Commons. 



Its ufes confift : ift. In healing wounds. In cale of a 



wound fuftained by a tree in tlie bark, being applied to the 



wound, it fecures it againfl: putrefaction, and enables it to 



heal, in the chLrurgical phrafe, by the firfl intention. 



2d. In accelerating the growth of timber, and producing* 

 young timber trees from the roots of old pollarxls. Cut 

 down an old oak clofe to the ground, cover the ftump with 

 the plaRer j young ilioots will fpring up from evef y part of 

 the circumference. Thin them out year after year as you 

 want them, leaving one for a ftandard. That one in ten 

 years will have made ,a (hoot, equal to what a feedling oak 

 would have made in thirty years. 



3d. In infufing youthful vigour into the oldeft fruit-trees 

 and enabling them to undergo tranlplantation, cut down 

 the tree in the fpring, almoft as low as the graft, cover the 

 Ihimp with the plafter, lay bare the roots, and cut them all 

 but the tap-root j The next fpring, after the ftump has thus 

 been made to puih out ftioots, cut the tap-root, and you may 

 trnnfijlant the tree, however old, with fafety. 



Mr. Forfythe's account of the preparation and its ufes 

 is faid to be in the prefs *. He is to have 1500 1. imme- 

 diately, and the remaining i \oo 1. after a certain time, 

 fliould the difcovery by that time have fulfilled, what it un- 

 dertakes for. 



* Mr, Forfyth's account is juft pub'.ifhed here, of %vhkli farther ex- 

 trads will be given, if it ajipear iiixciTary.
