Instructions to Observers in regard to Changes that are taking place along the 
Coast-line of the British Isles. 
1. Mention the part of the coast on which you report, and give its limits. 
2. State whether the coast is cliffy or low; whether rocky, sandy, gravelly, or 
muddy. If it is cliffy, give the average height of the cliffs, and, if possible, the 
nature of the material of which they consist, especially whether hard rock, chalk, 
clay, &c. State also the nature of the beach. 
3. What is the vertical range of ordinary spring-tides ? 
4. Is the sea encroaching on the coast? If so, state briefly the proofs of this 
change. 
5. Is the land gaining on the sea? If so, give shortly the evidence of such 
advance. 
6. Are there any artificial causes which tend to increase or retard the natural 
changes on the coast? For instance,are there any groynes along the shore, and if 
so, what effect have they on the travelling shingle or sand? Are the shingle, sand, 
or slabs of stone, removed for industrial or other purposes ?

Form No. I1.—Observations of Coast Changes. To be retained until there 
are some actual changes to be reported, after which the form should b 
filled up and returned without delay, in order that if needful a more 
careful survey of the changes reported on may be made by the Com- 
mittee of the British Association.

Instructions to Observers in regard to Changes that may take place 
along the Coast-line of the British Isles. 
A. When changes are actually observed to be taking place on the coast, either as 
to advance or retreat of the sea, it is very desirable that information regarding them 
should he forwarded as soon as possible. For example, when any fall of a portion of 
shore cliff occurs, note of the circumstances should be taken, with measurements 
(if that be found practicable) or estimates of the area or amount of material that 
has been dislodged. When any groynes or other artificial protections of the coast 
are washed away, this should also be reported, and likewise when any new groynes 
or other works on the coast are constructed. 
B. The Council of the British Association will be glad to receive any other 
information of which the observer may be in possession, bearing upon the changes 
that are taking place along the shore.
