This class of stations are situated as follows:—
| Whalsea Skerries | 148 feet | white, revolving every minute. |
| N. Ronaldshay | 180 feet | white, revolving every ten seconds. |
| Cromarty | 60 feet | red, fixed (in the town). |
Revolving lights, whatever the height, yield fewer returns than fixed, but are better than flash or red sectors.
We also thank those who, situated at still less likely stations, have nevertheless taken an interest in our work.

Kinnaird Head.—One year (1884); a blank schedule, valuable on negative grounds; 120 feet; white and red sectors, fixed.
