ing molftiirc to tlicplant whilft young, is 

 thus (k'prived of proper uutiimciit, and 

 ceafing alnioft wholly to grow, becomes 

 of no importance to the tree. " The 

 tap-root of ttic Oak will (lays Mr. Kiii<;ht) 

 lie adduced as an exception ;'' to which 

 lie re))lics, that in 'iO,000 trues of this 

 f|K;rics,lie never found a iin^le one pof- 

 felling a tap-root. And he concKides by 

 faj'ing, " As trees poli'cfs tiic power to 

 turn the upper furfaces of their leaves-, 

 and the points of their ilioots, to tJie 

 light, and their tendrils in any direction 

 to attach thenifelves to contiguous ob- 

 jects, it may be fufpefted that tlieir late- 

 ral roots are, by Ibme means, dire^-led to 

 auy foil in their vicinity wliich is btl't cal- 



culated to nourifli the plant to which 

 they belong; audit is well known that 

 much the ijrcater part of the roots of an 

 aquatic plant, which hris gri)wn in a dry 

 foil, on the margin of a lake or river, 

 have been found to point to the water ; 

 whillt tliofe of anotlior fpecies of tree 

 which thrives bell: in a dry foil have been 

 afcertained to take an oppofite direc- 

 tion : but the nfult of fome experiments 

 lead Mr. KniL'ht to conclude, that the 

 roots difperfe tliemfelves in every direc- 

 tion, and only becojue moll numerous 

 where they tind molt employment, and a 

 foil bell adapted to the fpecies of the 

 plant." 



NEW PATENTS LATELY ENPxOLLED. 



ME. BRACy CLARKr's (oiLTsPUP.-STREET), 



for certuia Impruvcmcnti upon Horji- 

 Jliocs. 



THIS invention is thus defctibed : — 

 The flioe lUflt' is made of two Uil- 

 tinct parts, \itiicli can at any lime be 

 /■feparated, viz. a Ihoe of elnttic iieel, or 

 other metal, nicely titled to the figure 

 and turnings of the foot, and fuiricicutiy 

 light in weight ; with lide and front clijis 

 or bands, bv which it is held rinnly to 

 the loot. This Ihoe lerves as a medium 

 of attaching another liioe, called the 

 w earing Ihoe, to the foot, and w Inch can 

 be fixed to it or feparated at pleafiue. 

 The wearing fhoc, which comes in con- 

 ta6t witii tiic ground, and receives the 

 attrition and ^vtar of the roads, is made 

 of iron or fteel, in the ordiiiai'y fonn of" 

 the iiorfe-ilioe, and can be renewed at 

 pleafure when worn out, as u is merely 

 fcrewed to the former by four or more 

 fufticient fcrews. Iir this way, the fitted 

 flioe is made to lalt many years, or even 

 the whole life of the hoi-ie. 



The fitted ilioc may be made of metal, 

 or of a mixture of metals ; but fteel 

 Iceins the molt fuitod to this piirpofe, or 

 iron, or iron cale-liardened, or filver 

 «i;ide claftic, or itecl or iron plated with 

 Other metiiU. This Ihoe is held to the 

 hoof by ftays or clips extending round 

 the whole or part of the fool, which 

 pievents the fijot cfcaping laterally or in 

 trout ; and thefc cLps or holds are part 

 ui tin- (lioe itlelf, or diliinct and fafiened 

 to it, and are made witti a llit or groove. 

 '^hn ubove tiutciuiij^s uidy p:eveiU the 



efcapc of tlie foot in front or fideways, 

 and it may be ftill fub;ocl to llide (jut 

 backwards ; and as the iieels are elaltic, 

 tender, and lenllble, no apparatus of the 

 above kind can be uled to prevent tliis 

 occurrence, or fevere compreliion of any 

 kiud : the patentee Uas therefore devifcil 

 another means of preventing this iucoii- 

 veiiience, by a bolt or bolts, or pin, or 

 fcrew, paliiiiy; through or near the front 

 or fide clips into the hojf, and which are 

 moveable with tiie gio\vth of the hoof 

 defcending along with it ; alfo, on fome 

 occahoiis, by bringing points through the 

 underli'^e of tiie ihoe upright into the 

 hoof to ferve the fame purpofe : fo that 

 one or ihc^ other of thel'e may be had 

 recourfe to, or both, sis the ideas of fe- 

 curity or fancy may fuggeft ; or a band or 

 bauds of fteel, or other metal, may be 

 confiructed to carry thefe points or bolts, 

 or fcrews, or plates, or hooks, and with- 

 out tiie principle of this conllruttion of 

 Ihoe being at ail departed from. The holes 

 for lodging the bolts or points of fteel, are 

 mafic in the hoof previously to their ap- 

 plication, with a fmall center-bit or 

 gouge, or palfer guarded, in fuch way as 

 to prevent the pofiibility of ita injuring 

 the (jiiick. A iLout I'crcw or toothed rack, 

 or fteel lliaft, or other contrivance of 

 this dcfcription, feiTcs to carry thefe 

 points, and to regulate their elevation, 

 and alfo deiccnt along with the growth of 

 tiie hoof: a lliding bolt and pin, or fcrew 

 and nut, may alio fcrve the fame pur- 

 pofe. 

 It is added iu the fpecification, that
