Account of watching waves at the natural arch at Gonnamaol [Gunamul, Miùghlaigh/Mingulay] describing them as 'a glor[ious] sight...the sea churned purely white against the rocks like divine snow on a mount[ain]side'. He observes the plentiful bird-life there 'The birds in thous[ands]nay millions fly hither and thither at times dark[e]ning the very air and along with the dizzy height on which you sit mak making (sic) you still more dizzy till you feel your position anything but safe or prudent. To my thinking there is nothing grander in Nature than the warring of the elements.' He describes the varying aspects of Gunamul including that some layers of rock are 100 feet thick while some are only 1 foot.
