HUNA, CAITHNESS-SHIRE.—On receipt of a telegram from Brougb, the Life-boat Caroline and Thomas was launched at 6 P.M. on the 21st June, proceeded to the Fentland Skerries and found the fishing lugger Magdalen Hughes, of Kirkcaldy, stranded on the S.W. point of Little Skerry. Her crew had landed, and the Life-boat men assisted them to savetheir nets and other materials, it bung probable that the lugger would become a total wreck.
