JERBOURG AND ITS FORTIFICATIONS. 265 



was built in 1786, as mentioned on page 16 of a manus- 

 cript book by M. J. A. N. De Magnac, in the possession of 

 Miss E. Carey ; that this is the tower marked on the 

 1787 map, and again with the signal-post adjoining, on the 

 map of Jacob's history under date 1814; that here Captain 

 White had his quarters. 



In the course of exploring this district, I have found 

 four curiously shaped structures ; two on the west side were 

 examined by members of this Society during the excursion 

 in June ; there are two others on the east slope. They are 

 all similar in arrangement, the ground-plan being a segment 

 of a circle, the roof arched and partly constructed of stone 

 work. Those on the west are small. It was suggested that 

 they might have been stables, but they were not large 

 enough even for a sheep-fold. Those on the east are larger, 

 and are built in connection with the southernmost of the 

 trenches. All are constructed with considerable care, the 

 walls of native rock and stone-work ; but the occurrence of 

 pieces of brick in two of them shows that they are of modern 

 origin. My idea is, that they were a kind of sentry-box 

 or permanent shelter into which men on patrolling or sentry 

 duty could occasionally retire, so I should date them about 

 the beginning of the nineteenth century, when real militia 

 duty was cheerfully done by the inhabitants of Guernsey, 

 who were in constant dread of an attempt at landing by 

 the French. 



In conclusion, members of this Society and everyone 

 interested in antiquities, while rejoicing in the prosperity 

 of Guernsey, and acknowledging the enterprise displayed 

 by its inhabitants in bringing so large an area under 

 cultivation, must feel thankful that a few spots have been 

 left almost in a state of nature, and so some of our finest 

 dolmens and these ancient trenches have been preserved to 

 throw light upon our ancient history.
