Letter from J. Rogan, to Donald McLean, dated 21st. November 1854. New Plymouth 21st. November 1854. My dear Sir, I duly received your note from the steamer while off this place; and as Cooper embarked, I left it with him to tell you the state of affairs up to that period. The surveys of the Hua have been proceeded with at a slow pace, owing to repeated interruptions from the Puketapus, who have daily raised reports of attack, which have not yet been realised.
