horse, or for a villain's neck, it turns it out complete in less time 

 than I take in giving you this explanation. The expense of ma- 

 king one-inch cordage, is one cent per pound. 



Here are new improvements on the grist-mill, grinding grain 

 with great speed and perfection, reduced to a small space in size 

 and with a great saving of labor and expense. 



Yonder is a machine called a magnetic engine — a new appli- 

 cation of the power of electricity, which you all know Franklin 

 first drew from the clouds, and showed its properties by the in- 

 vestigations of his own great and inquiring mind. I remember 

 sitting in company with men who laughed at what was term- 

 ed the folly of Fulton, who attempted steam navigation. 

 Where is not the triumph of our country complete in the success 

 of his invention 1 Perhaps such fortune awaits this discovery. 

 It proposes to work by a galvanic battery, and by its magnetic 

 power to serve in the place of steam, with an economy of space 

 and labor, making a saving of nearly one-half. It is yet incom- 

 plete ; it merits scrutiny. 



There is Bishop's improved carding-engine, for wool and 

 cotton. It claims and appears to be a great improvement, re- 

 quiring one-third less power and one quarter less space in the 

 factory, and with other points of economy. 



There is Eastman's improved Throstle frame for spinning cot- 

 ton. It dispenses with the drum and bands — and gives motion 

 to the spindle with increased ease and economy in space, and 

 with one-half the cost. 



Here let me show you a valuable plan for the ventilation of 

 ships — it is in the nature of a self-acting pump, like an inverted 

 syphon or an ox bow, to draw out the foetid air from the hold of 

 the ship. Valuable when we consider how many of the poor 

 immigrants die with ship-fever from bad ventilation on board 

 our vessels. 



This cast iron wheel, which is an object of no small importance 

 to railroad companies, is well deserving of attention. This spe- 

 cimen, the centre of which is of cast-iron, and with a wrought-
