MINUTES OF PEOCEEDINGS OF 
attack, extending to details of construction of batteries, saps, and field 
magazines, the distance of the first approaches, and their subsequent 
development. These questions appertain chiefly to the duties of the corps of 
Eoyal Engineers, and have doubtless engaged the attention of the officers at 
the head of the instruction of that branch of the service. The Committee, 
therefore, will not enter upon them. 
The Committee cannot conclude their report without expressing their 
obligations to the officers of the Eoyal Artillery and Eoyal Engineers who 
were employed in connection with this experiment. They also derived 
much assistance from the electric telegraph and from the photographic 
arrangements superintended by Captain Boileau, E. E. The County 
Constabulary, under Colonel Mackay, rendered on this, as on the two 
former occasions, most valuable services.
