 mannfactures. The experience of other countries, the best prac- 

 tical guide in our own, demonstrates, that such open marlvcls are 

 eminently nsefnl in their connexion with agriculture. Under judi- 

 cious regnlatioiH and salutary provisions for (he preservation of 

 order, and securing fairness in the conduct of business, they may 

 doubtless be rendered advantageous to our citizeris, allowing choice 

 and competition in purchasers, without the disturbance of those 

 scenes of tumult and Wlood-shed which disgrace the riotous and de- 

 based population of other lands whenever assembled

The inconvenience and su '"•ring, which arise from cold (eet, 

 w' "'e riding in stages in the winter, are obviviicd in the north of 

 France, by means of pewter tanks, made after the manner of water 

 plates, fitfed to the bottom of the stages, and tilled with hot water 

 at each stopping-place, which impart not only warmth to the leet 

 in the coldest weather, but a pleasant glow of heat through the 

 whole stage. 



PLUMBAGO CRUCIBLES. 

 A friend has just sent us a black-lead crucible, manufactured 

 in Boston. The black-lead, or Pluinbago, is from a mitie in Stur- 

 bridge, Mass., owned by a gentlema.i of Boston, who is engaged in 

 working it with every prospect of success and profit. 1 his crucible 

 is, in every respect, equal to any manufactured \\i Rurope. It is 

 pleasing to notice the successive steps, which our country is taking 

 in the arts. Every day brings with it some new discoveries in our 

 mineral treasures, or some use of them, in the various occupations 

 of life. This person has been instrumental, it seems, in bringing 

 into use this mineral, which heretofore was undoubtedly consider- 

 ed useless rubbish ; and we hope his enterprise will be amply re- 

 warded. We are glad that men of science and capital, are begin- 

 ning to turn their attention to the mineral resources of New-Eng- 

 land. It will be found that she abounds in almost every thing of 

 the kind, which is needed in the common arts, and which, when 

 fully developed, will be an almost inexhaustible source of wealth 

 and comfort to her cifi.un*. Wc ar; .remised a more particular 

 acco !.il of the above mentioned mine and manufactory for a future 

 number.
