N.B. 
In every case in which masonry is used for defence, whether 
wholly or in part, or as an inside wall to the rampart, or as the 
rampart itself, the fact should be mentioned. 
The existence of mounds or tumuli entirely within defensive 
enclosures should be noted. 
When a fortress is provided with more than one rampart or 
wall, the fact should be recorded, as also when the enclosed area — 
is divided by transverse banks. It should also be noted whether 
such additional ramparts or their ditches are intermittent or 
continuous, and whether the entrances are direct or of a tortuous 
character. 
It is specially desired that the position of each work be 
indicated by noting the number of the sheet of the O. S. (6-inch 
scale) in which it appears, and by giving the name of the nearest 
town or village. 

Plans traced from the 25-inch O.S. maps should, if possible, 
be sent. Ramparts and ditches should be clearly indicated, as in 
the accompanying illustrations, as well as the O. S. levels, and 
accurate sections will be of great service. Precipices, as at Comb 
Moss, and abrupt slopes, as at Mam Tor, should be indicated as 
shewn on the accompanying plans, and named. 
Although lists of all defensive earthworks and enclosures will be 
welcomed, it is to be borne in mind that plans and sections of them, 
based upon personal examination, are particularly desired. 
Though not strictly within the scope of this enquiry, it is 
suggested that all medizeval castles should be included in the — 
schedules, since many of them originated in earthworks of Class E. 
Assistance will be duly recorded in the report which the 
Committee hopes to present to a future Congress of Archeological _ 
Societies,
