One of Rupert's principal cares was the relief of the distressed Cavaliers, who looked to him as their supporter and representative. Charles II has often been blamed for not relieving the wants of so many of those who had suffered for his father. Probably he was callous to suffering which he did not directly witness, but it must be confessed that his position was a hard one. He could dispose of very little money, and he was much bound to the Presbyterians who had restored him to the throne. His pledges to them prevented him from upsetting much of the existing arrangements, and consequently hampered him in the relief of the Royalists. Such of these as were in want turned to Rupert, sure of a hearing and of such aid as he could give, whether it were in money, or in intercession with the King. The State papers are full of their petitions, which generally refer to Rupert as their guarantor; indeed his certificate seems to have been regarded as the necessary hall-mark of their authenticity. In 1660 he came to the defence of 142 creditors of the late King;[11] and we find him pleading for a certain Cary Heydon, and other people, at the commission for indigent officers.[12] One very striking instance of his justice and good memory occurred just before his death. A certain member of Parliament, named Speke, had been accused of conspiring for Monmouth against the Duke of York, and was summoned before the Council Chamber. He defended himself ably, and quoted his former services to Charles I. Rupert suddenly stood up, told the King that it was all true, "and added one circumstance which Mr. Speke had thought it not {337} handsome to mention," namely, that when he, Rupert, had been in great want of money for the King's service, Speke had sent him "1,000 pieces"; and had been so far from asking repayment, that the Prince had neither seen nor heard of him from that day to this. The accusation was promptly dismissed; and on the next day Rupert invited Speke to dinner, when he "entertained him in the most obliging manner."[13] In December 1662 Rupert became one of the first Fellows of the Royal Society, of which the King was also a member,[14] and their common interest in science formed an additional bond of union between the cousins. Rupert had both a forge and a laboratory in which he himself worked with great zeal. The King, with his favourite Buckingham, was wont to lounge in and sit on a stool, watching his energetic cousin, with keen interest. Sometimes the Prince would weary of their chatter, and he had a short and effectual way of ridding himself of them. He would coolly throw something on to the fire which exhaled such fearful fumes that the King and courtiers would rush out half-choked, vowing in mock fury that they would never again enter the "alchemist's hell."[15]
