Of the Bolleit cave it is said that the roof will fall in and crush any one who remains there more than a certain number of minutes.

[A mysterious cavern] at Bolleit, in the parish of Buryan, which was so large and perfect in the time of the Great Rebellion, that Cavaliers were for some time concealed there; where, like the prophets of old, they were fed by Mr. Levellis of Trewoof, until opportunity offered for them to return to the King's army.

Beyond the Nine Maidens seaward is the great serrated range of granite rocks, Carn Galva, so conspicuous an object for several miles in nearly every direction. Somewhere amongst the rocks in this carn is the Giant's Cave, in ages long gone by the abode of a giant named Holiburn. My informant could not point out the locality of this cave, her knowledge of it having been derived from hearing her "old man," now dead, speaking about it some thirty or fourty years ago. It is of the rarest occurrence to hear the name of a giant mentioned in the recital of any oral tradition in this district; and, as a general rule, even those who best remember the stories current in their childhood have no recollection of ever having heard the giants alluded to by distinctive names.
