NOTES ON THE PREPARATION OF PLANS AND 

 SCHEDULES. 



In order to secure the uniformity of treatment which is most desirable, 

 the Committee makes the following recommendations. The methods 

 here advocated offer no serious difficulty to the amateur surveyor ; at the 

 same time it will be understood that more elaborate surveys are much to 

 be desired whenever circumstances permit. 



i. A definite area should be undertaken by each worker ; this being 

 settled, the 25m. O.S., or largest available scale map, for the district 

 should be consulted, and tracings made of each defensive work thereon. 

 Local knowledge alone can determine what works, if any, are omitted 

 from the O.S. These, of course, must be surveyed and plotted inde- 

 pendently. 



2. Although accurate so far as they go, the 25m. O.S. plans in most 

 counties need additions of details which appeal to an archaeologist more 

 than to a surveyor. Sometimes, too, it will be found that shading to 

 indicate slopes has to be added, and it is very desirable to give the 

 ordnance level of the fortress and the contours of its surroundings. These 

 latter can be found on the 6in. O.S. maps, though absent on the 25m. 



3. As "homestead moats" (class F) are so exceedingly common in 

 some counties, it is only considered necessary to plan a few typical and 

 all exceptional forms in each county. Dry moats should be indicated in 

 the same manner as any other earthwork by suitable hachures. For 

 water moats the O.S. method should be used, with the addition of shading 

 for water. 



4. To facilitate comparison, it is very desirable that all plans should 

 be drawn to the 25m. scale. It has been found necessary, in order to give 

 as many examples as possible in the space here available, to reduce the 

 scale of the foregoing plans to one-half the 25m. scale. 



5. Sections across the site should be drawn to the same scale as the 

 plan, and vertical heights should be natural and not exaggerated. If the 

 scale is too small to show vertical heights, the scale of the section may be 

 enlarged, and this fact stated. 



6. Detailed sections of portions of the work should also be given ; 

 these will require various scales according to the subject, and the scale
