At this time interest in Guiana and its precious metals had revived. Ralegh had some morsels of merquisite he had himself picked up assayed by a refiner. The man found gold in them. These, or other specimens of Guiana ores, Sir Amias Preston, his old adversary, had seen. Preston had extolled them to Cecil. Ralegh may have discussed their virtues with Cecil in the Tower at one of the interviews in the laboratory, when, he complains, the Minister would listen, inquire, talk of the assay, hold out hopes, and then retreat into an _arrière boutique_, in which he lay unapproachable. A letter to Cecil, with the uncertainty of date which breaks the hearts of Ralegh's biographers, says: 'I have heard that Sir Amias Preston informed your Lordship of certain mineral stones brought from Guiana, of which your Lordship had some doubt--for so you had at my first return--secondly, that your Lordship thought it but an invention of mine to procure unto myself my former liberty; suspicions which might rightly form into the cogitations of a wise man.' He assured Cecil that a mountain near the river contained 'an abundance sufficient to please every appetite.' Once he had thought the stones valueless, like other merquisite. He had been convinced of his error by the refiner, who was willing to go and be 'hanged there if he prove not his assay to be good.' To avert suspicion that he meant to become a runagate, Ralegh was ready not to command, but to ship as a private man. He repeated his strange offer to be cast into the sea if he should persuade a contrary course. The cost would be no more than £5000. 'Of that, if the Queen's Majesty, to whom I am bound for her compassion, and your Lordship will bear two parts, I and my friends will bear a third. Your Lordship may have gold good and cheap, and may join others of your honourable friends in the matter, if you please. For there is enough. The journey may go under the colour of Virginia. We will break no peace; invade none of the Spanish towns. We will see none of that nation, except they assail us.' His intention was to melt down the mineral on the spot into ingots, 'for to bring all in ore would be notorious.' In 1610 he had written to a trusted friend of James, John Ramsay, then Viscount Haddington, and later Earl of Holderness, with similar proposals. He would follow Ramsay as a private man, or others, and if he recommended a different course was willing to be drowned. Then, 'if I bring them not to a mountain, near a navigable river, covered with gold and silver ore, let the commander have commission to cut off my head there.' Or he would give a £40,000 bond to boot. [Sidenote: _Overtures to the Council._]
