by the use of water-falls in the down-cast shafts, previous to lighting the furnaces. By 

 this mode we presume such a degree of ventilation may be effected, that the furnaces may 

 be lighted with safety ; but if such a force of current cannot be produced by a water-fall 

 as will restore the ventilation fully, we would advise that the air should be taken direct 

 from the down-cast shafts to the up-cast, for the purpose of lighting the furnaces with 

 safety, and that the ventilation should be restored in the different districts in succession 

 through the pipe drifts. 



3d. You will please to estimate the probable expense which the restoring of the colliery 

 to a regular working state will cost. 



We estimate the cost of restoring the ventilation and putting the pit into the same work- 

 ing state as before the accident, to be about 1,2001. 



We are, Sir, 



Your obedient Servants,

Wallsend Colliery, \9tk August, 1835. 

 To Messrs. Geo. Johnson, Nicholas Wood, Thomas Morriss, and Matts. Dunn. 

 Gentlemen, 



The measures recommended in your report of the 18th ultimo, for 

 restoring the ventilation of the Bensham Seam Workings in this Colliery, having been car- 

 ried into effect, as far as circumstances will permit, until the furnaces are re-lighted, I 

 have, therefore, to request that you will be so good as to examine the present state of the 

 workings and the ventilation thereof, and report on the following points. 



1st. As to the present state of the general ventilation of the colliery, and also of the 

 several currents of air, and say whether you find them in such a state as to admit of the 

 furnaces being lighted with safety, or if you should not find the returns in such a state as 

 to admit of the furnaces being lighted with safety, you will please to point out such steps, 

 as you may think best calculated for accomplishing that object in the shortest time. 



2d. In the event of your finding that the furnaces may be safely lighted, you will please 

 to point out what measures should then be adopted for restoring the colliery to a safe work- 

 ing state with the least possible delay. 



3d. You will also point out, in which of the divisions of the workings, coal work ought 

 first to commence, and,
