110 Notice of some New Electrical Instruments. 



No. 6. — The French Creek division, connects the Conneaut Lake 

 with the Allegheny River at the mouth of French Creek, and passes 

 through Crawford, Mercer and Venango. Length 45 J miles. Lock-

18 by 90 feet in the chamber, except the outlet lock at Franklin which 

 is 22 by 120 feet. 



The aggregate length of the Branch Canals is 311 £ miles exclu- 

 sive of all side cuts. The lockage is 745 feet ; making, when add- 

 ed to the main line, 587 miles of canals, with 1923 feet of lockage. 



The total length of canals and rail roads constructed by the state, 

 is 706 J miles, overcoming 5339 feet of rise and fall. 



Most of these works are completed, and it is confidently expected, 

 that all will be finished at an early period next season. The limits 

 which I have prescribed to myself, do not permit me at present to ex- 

 plain and account for the difficulties which have been 

 in their construction. They may be inferred from the fact, that the 



appropriations for the works which I have described have already ex- 

 ceeded $18,000,000. 



1 have now done with the dry details of compilation. When I 

 commenced them, I expressed a belief that her sister states were 

 hardly aware of what Pennsylvania has been doing. She has moved 

 onward in her course, with that quiet determination which always 

 marks extraordinary strength, and without appealing to foreign aid, 

 has triumphed by the energy and resources of her own citizens. Nor 

 have Pennsylvanians been content with those works alone which have 

 been constructed by state authority. The Schuylkill, Union and Le- 

 high Canals, and the almost innumerable rail roads which traverse the 

 eastern part of Pennsylvania, testify that the difficulties interposed by 

 our rugged mountains, have only acted as incentives in the pursuit of 

 wealth and power.

TO THE EDITOR. 



Dear Sir. — I offer for your Journal a description of an electric 

 syringe, which if it does not prove a useful instrument to the electri- 

 cian, will perhaps afford him some amusement. A rough drawing 

 of it will serve to explain it better than a bare description.
