A CANTERBURY FARMER,3
Tiie difficulty which has arisen in Australia in regard to the carapli cations in earraa kine sheep can now bo'surnberered with the past. A pat ent has been granted to Mr Clement 0. Derretk, formerly a Bheep farmer in tbe Hororata district, but now a a resident of Obristohuroh ; for an ad justable pair of washers combined, whiob are attached to tbe cheep's *ar io such a permanent way as to dn po<?e of the possibility of sheep-steal-ing I- a pair of washers or piate* adapted to be ola »ped upon ton two sid.lß of the e*r hy CxiatCGiog means, passing through a suitable hole in tbe ear, provided for tbe pur purpose. It is the object of the in vention to provide' a contrivance which, when once attached to the ear cm be removed only with great diffi Culty, necessitating such laborious nnd skilful use of tools a* to render such
removal impracticable. Ia c.uvyin g out this object tbe washers aud thsir coanecting meana are pressed or stamped from sheet metal. Each washer is former with an indentation in one of its side faces, which consti, tutes a projection or shank upon the other face. Tbe other washer also is formed,with an indentation in one of of itq faces, constituting a socket, formed with a central hole to receive the end of the shank of tbe other washer. Tbe arrangement \s such that when the washers are placed in in position tbe application of pressure to the connecting means will cause the end of the shank to spread into' a hollow or bowl shaped formation of the indentation in thu otber washer, and so serve to rivet the firmly upon the ear. By tmo o>..
struotion it'will be seen t'>at;, should the end of the sbink b* cv away by drilling or filing, is «vill ■> ill retain s*s grip, by reason of 'the fac tfiaD"th- fsides of tbe shook will still remain ex panded against the concave under sur face of the other indentation. If though desirable, tha washers or digc-J in stead of being mida Heyararr, may OOasi'tof on« piwoo of uHtal ,b<m round in the middle of its l?ag h, so
o , embrace tbe ro-'pective opposite ides ol tbe ear
Tbe above particulars will suffice to show all interested in Bheep farming that they will be in a position now to adopt a very cheap but thoroughly efficient meanti of earmarking their shaep lodeed, tbe mechanical ear marking device that Mr 0. 3 Derrefc has gone to much trouble and nxpense
to perfect and patent will t>3 so sim ■ pie, cheap and easy to work that farmers and breederg will wonder why someone has not taken the trouble to think it out before this, and so save vast amounts in labour. The work is done instantaneously, and the person operating tbe pliers can earmark as many sheep aud lambs as can be handled, and so permanently assure
