Thursday, 5 p.m. About eight o'clock last night, three bushrangers attacked Sharpe's Store, Lower Pyramul Diggings, about twelve miles from this place. The bushrangers attempted to force the door; they had partially succeeded, when a servant of Mr. Sharpe, named Massan, attempted to secure it, and, in doing so, was shot by the robbers, and died within half-an-hour. Mr. Sharpe returned their fire and is supposed to have wounded one man, as a gun besmeared with blood and indented with shot marks, was found outside the door. The robbers retreated after Mr. Sharpe fired, and, owing to the darkness of the night, it is fear they cannot be identified. The affair has caused great excitement. The police are actively searching for them.

Tambaroora. Friday evening. The inquiry into the murdered Chinaman, a digger, commenced to-day, and was adjourned for a week for the production of further evidence. Mr Charles Suttor's shepherd stated that whilst approaching a secluded portion near Triamble Creek in quest of water, he observed deceased's knees above water, his head and feet being submerged. Large stones were lying on his shoulders and head. Senior-constable Kelly traced boot prints on the blood-bespattered stones around. Seventeen heavy dagger looking wounds about the head, heart and chest, any one sufficient to cause death ; also a lacerated gash on the stomach, causing eviceration. Portions of deceased's clothes were found lying on the bank. The body is in a state of advanced decomposition. It was interred, surrounded with sheets of bark, near the spot. No clue as to the perpetrator.

Tambaroora. Thursday. The half of the police magistrate's quarters at Hargreaves was burnt down this morning. The estimated loss of the Government is about 150 pounds, and Mr. Scott's personal property over 300 pounds. The supposed cause was the over-heated flue of the drawing-room chimney. The building being all weather-board, and the fire occuring between 2 and 3 a.m., not a single article could be saved. No lives lost.

Tambaroora. Monday. Miss Isabella Mary Louisa McLean, 21 years old, was accidentally killed on Friday, the 19th instant, by the capsizing of a cart she was driving. It is surmised that the horse bolted and capsized the cart. Her body was found about ten feet distant from the cart. Life was quite extinct, with marks of severe bruises on the chest, neck, and collar-bone. She was buried on Sunday, and followed to her grave by an immense concourse of people, there being not less than two hundred horsemen, and a great many vehicles. Although the horse was not dead when the accident was discovered, he only lived two hours.
