Part One. West Briton and Cornwall Advertiser. Friday 21st February, 1851. THE CORNWALL RAILWAY - We understand that Mr. BRUNEL has received instructions to survey the Cornwall line of railway from Plymouth to Falmouth, in order to ascertain and report the very lowest possible cost at which it can be constructed. SAFETY PLUG FOR BOATS - Mr. J. H. GEACH, watchmaker, of Fairmantle-street, Truro, has invented a contrivance in the form of a brass screw and nut, to be used as a plug for boats instead of a cork as at present. It is an ingenious though simple invention, and appears to be admirably adapted to answer its purpose. We understand that he intends to forward it for the inspection of the admiralty. ST. STEPHENS IN BRANWELL INSTITUTION - The annual dinner of this institution took place at the house of Mr. JACOB JENKYN, on Monday last. The Rev. J. CROSSLEY occupied the chair, and was supported by Mr. SMITH, of Ventonwyn, and other gentlemen of the neighbourhood. The officers for the ensuing year were elected, and the usual business transaction after which the health of the chairman and other toasts were drunk. The company then adjourned to the schoolroom, where a lecture was delivered on "Phrenology," by Mr. REUBEN THOMAS, of Roach, and the able and spirited manner in which it was treated elicited frequent applause.

FESTIVE ENTERTAINMENTS AT HELIGAN, &c. - On Friday last, the children of the St. Ewe school, ninety-six in number, were sumptuously regaled at Heligan, the seat of Mr. TREMAYNE, in celebration of the marriage of Miss Tremayne with the Rev. J. T. BOSCAWEN, which took place on Thursday the 13th instant. It may be observed that the St. Ewe school, which is entirely supported by the liberality of Mr. Tremayne, has received much attention from Miss Tremayne, who, by her kindness has greatly endeared herself to the children. On her farewell visit to the school, she was presented by the children, with a handsome token of their esteem, which met with a most sincere and heartfelt acknowledgment. On the 12th instant, a ball and supper were given at Tregothnan, by the instructions of the Earl of Falmouth, to some of his tradesmen, and the tenantry of his estates in the immediate neighbourhood, to celebrate the marriage of the Rev. J. T. Boscawen (cousin to his Lordship) with Miss Tremayne, of Heligan. The festivities were greatly enjoyed by those assembled. SCHOONER LAUNCHED - On Thursday the 13th inst., a fine new schooner was launched from the building yard of Messrs. JOHN and MARTIN CLEMENS, at Newquay, of the burthen of about 130 tons, called the "Tower," and belonging to Capt. JOHN CARTER and CO. She went off in gallant style, amidst the cheers and congratulations of a vast number of spectators. This vessel is well adapted for the coasting or foreign trade. DISASTERS AT SEA - About a mile off Port Mellon Cove, in the Parish of Mullion, there may be seen from the cliff the top mast of a vessel upright, about four feet of which is out of the water. On the 8th instant, SAMUEL HICHENS and THOMAS STEVLING went out to it in a small boat, but the weather being boisterous, they could not make out what vessel it was. REDRUTH COUNTY COURT - At this court on the 13th and 14th instant, the following case was heard which involved a serious charge of "kitting." TRESTRAIL and HICKS v. GARLAND. This was an action to recover the sum of GBP40. 3s. 4d., claimed by the plaintiffs as their proportion of certain ores raised in Carn Brea mine in the month of October last. The defendant was sued as one of the adventurers in this mine. The plaintiffs were represented by Mr. THOMAS ROGERS. Mr. STOKES, on the part of the defendant, admitted that his client was properly sued as an adventurer; but denied being indebted to the plaintiffs on the ground that they had forfeited all claim to payment for any ores raised by them, by reason of their breach of one of the rules or bye-laws of the mine, which declared all ores forfeited in cases where the tributers mix any other ores with their own. To prove their case the plaintiffs were examined. They stated they took a pitch of Captain LINTON (one of the agents of the mine) subject to the rules of the mine; that they worked at the eastern end of the pitch close against the boundary shaft about a week, and broke five or six barrows of ore, which they wheeled back to the western end of the pitch. This was away from the shaft about thirty fathoms; that they afterwards went to work at the western part of the pitch near to the cross-cut, where they worked the remaining part of the month; that from both places they obtained about twenty-nine barrows of ore, which they put together in one pile; and that the tribute they had agreed for was 13s. 4d. in the pound. On cross-examination by Mr. STOKES, they admitted this tribute to be a very high one, and that it was agreed to be given, because their pitch was well-known to the agents to be an unproductive one. They denied they had been under-ground at night at any time during the month, or that they had thrown "attle" or loose stuff over their pile of ore to conceal its colour. They admitted that Captain Bennetts had looked at it, and remarked that it appeared to him to be two sorts of ore in the pile, but they explained to him that they had broken a red colour ore at the eastern part of their pitch, and a grey ore at the western part, and shewed him where they broke them; that he appeared satisfied and that until six weeks after, when they went to be paid, no complaint was made that they had taken the ores of certain tut-men working a short distance from them. Mr. Stokes, for the defence, called HENRY PAUL, WILLIAM PAUL, ANDREW HARRIS, EDWARD, TREVEAN, JAMES HARRIS, THOMAS WHITE, THOMAS MARTIN, RICHARD ANNEAR, Mr. R. PIKE, purser of the mine, and Messrs. LINTON, ROBERTS, and BENNETTS, three of the agents, whose evidence is embodied in the following statement. That on the 18th of October, certain tut-workmen, who were working in or near the forty-six fathom level, missed about a ton of ore from their pile; and that the quantity taken out was so remarkable they could not help missing it. Suspicion first fell on a man called CANNON, but on examining his work nothing could be discovered to justify that suspicion. Captain Bennetts then proceeded to examine the plaintiffs' pitch, and on approaching was attracted by the sound of "spalling;" a circumstance quite unusual under ground, and which was discontinued on his arriving near the place. That on examining the plaintiffs' pitch, two sorts of ore were discovered, and the accounts of the plaintiffs differed as to where they got their ores. The ore discovered in the plaintiffs' pile corresponded with the ore in the tut-workmen's pile, which was of a peculiar black colour. The plaintiffs' pitch was examined by men who had worked there before, and also by the three captains, who spoke to the work that had been done there, and the improbability of their having found the ore there. It further appeared that at midnight on the 17th of October, the plaintiffs went under ground, a thing quite unusual when there were only a pair of tributers working a pitch; and on the following morning they were seen coming from the shaft with their faces very black, evidently shewing they had been working about an ore of that colour. It also appeared that a day or two previous, one of the plaintiffs were seen examining the tut-workmen's pile of ore, and taking some of it and putting it in the belly of his shirt, and on leaving desired one of the men called ANNEAR, to be sure you don't tell the captain I have been down here." The ore was taken from the pile of the tut-workmen between ten and six o'clock of the same night on which the plaintiffs were known to go down, and during which period there were no tut-men working. Afterwards, the respective piles of ore of the tut-men and the plaintiffs were brought to "grass," and examined and tried, and found to be exactly similar. On the discovery being made, the plaintiffs were at once discharged from the mine, and told they had forfeited all claims to payment for any ores. The rule referring to the case was read by Captain LINTON, and runs as follows:- "If any ores be found amongst the tributers' ores which do not belong to their respective pitches, all such ores will be forfeited to the adventurers." Some discussion took place as to the proper construction of this rule, which appeared to be rather ambiguously worded as to whether it intended that all the ores found in the pile should be forfeited, or only the ores that did not belong to the pitch. On this point his Honour decided against the plaintiffs, and eventually gave his judgment in favour of the defendant, observing that the chain of circumstantial evidence against the plaintiffs was too perfect to admit of a doubt. The case excited great interest and occupied nearly the whole of the first day. SMUGGLING - On Monday last, WILLIAM REDBOURNE, an American, and a seaman called SHELLY, two of the crew of the schooner "Copy," of London, were charged at Crotch's hotel, Hayle, before the Revds. URIA TONKIN and T. PASCOE, magistrates, with having smuggled seven and a half gallons of brandy. They were convicted and fined GBP100 each, and in default of payment were committed to the county gaol for six months. The charge was preferred by instructions of Mr. JAMES, Comptroller of c=Customs at St. Ives. Mr. PASCOE appeared for the prisoners. FORGERY - Mr. DANIELS, who some time since forged a receipt for GBP50, in the name of Mr. BOASE, of Liskeard, in the case of shares in Wheal Mary Ann, has been tried, found guilty, and sentenced to seven years' transportation. TRURO POLICE - On the 12th instant, JOHN HILL was committed to the House of Correction for three calendar months to hard labour, as a rogue and vagabond, for wandering in the public streets, and obtaining charitable contributions under false pretences. The fellow went into the shop of Mr. JAGO, tailor and mercer, St. Mary's-street, and pretended to be deaf and dumb, but as soon as he was given into custody, and his begging brief taken from him, he showed that he could speak fast enough. On Saturday last, WILLIAM MARTIN was committed for fourteen days to hard labour, as an idle and disorderly character. JAMES THOMPSON was charged with being an impostor, going about the town and asking for lodgings under false pretences; but no legal offence was proved against him, and he was discharged. On Monday last, ANN PLACE was committed for fourteen days to hard labour in the House of Correction, for being a disorderly character. On Tuesday last, BENJAMIN HOSKIN, who represented himself as of St. Just, was committed for three months to hard labour as a rogue and vagabond, and for obtaining charitable contributions under false pretences. He stated that he was the master and owner of a vessel which was wrecked, whereby he had lost GBP600, and therefore solicited charity. On Wednesday last, JOHN LOWRY, tailor, was committed for trial at the next assizes, for stealing a piece of cloth, &c., from Mr. JAMES HODGE, tailor, Walsingham-place. KITTY LOWRY, wife of JOHN LOWRY, was likewise committed on a charge for stealing two calico sheets, one table-cloth, three calico pillows, one pair of silk gloves, and one window blind, the property of Mr. JAMES SANDERS, of the Ship Inn.
