remove the difficulty. We proceed to suggest the 

 means by which, as we conceive, the difficulty can 

 be best met, admitting, as we do, that it is not capa- 

 ble of being wholly removed. The only useful pass 

 which can be here constructed is one which will be 

 effective only at the following periods; namely, in flood 

 time ; secondly, during the weekly close-time when 

 the mill stops work ; and lastly, during the winter- 

 season ; and these opportunities, under all the cir- 

 cumstances, may be considered sufficient. 



Let a similar incline, concave on the surface, be 

 built against the weir, but finishing about a foot be- 

 low the crest ; here let an opening be made, in due 

 conformity with the provisions of the 5th and 6th 

 Victoria (doing no injury to the water-power of the 

 mill) ; the opening when completed should be, say, 

 nine inches in depth, and about four feet wide ; if an 

 oaken or metal sill be imbedded in the masonry at 

 the top of the inchned plane, grooved so as to take 

 a metal plate or bevelled piece of timber adapted to 

 the groove, in such way as to range with and con- 

 tinue the inclined plane, and of such height (that is 

 to say nine inches) as will range exactly level with 

 the crest of the weir, a pass will be formed, and no 

 injury whatever will be done to the water-power of 

 the mill. This pass will be effective in flood time, 

 and will then act without requiring any attention ; 

 during the weekly close-time, when the mill stops, 

 the passage can be opened under the provisions of 

 the Act, and during the general close-time, we ven-
