Of his travels nothing appears to be known; but he doubtless followed the route usually taken, through France, Germany, and Italy, by young Scotsmen of family, who, it need scarcely be said, were almost always sent to finish their education by visiting foreign countries. Fletcher knew French, but with regard to Italian Lord Buchan mentions a curious fact. ‘He had,’ says Lord Buchan, ‘acquired the grammatical knowledge of the Italian so perfectly as to compose and publish a treatise in that language; yet he could not speak it, as he found when having an interview with Prince Eugene of Savoy, and being addressed in that language by the Prince, he could not utter a syllable to be understood.’ Having returned to Scotland, he was, in June 1678, sent as one of the members for Haddingtonshire to the Convention of Estates which met that summer. His colleague was Adam Cockburn of Ormiston, a fine gentleman of the old school, but one of the most virulent Presbyterians even of that day. It is to be observed that the rolls of parliament have the name of ‘James Fletcher of Saltoun.’ It appears, from the Official Return of Members (published in 1878) that the original commissions for Haddingtonshire have been lost; but there is no doubt whatever that the rolls are wrong, and the name ‘James’ appears by a mistake instead of ‘Andrew.’ This Convention of Estates, in which Lauderdale was Lord High Commissioner, sat from the 26th of June to the 11th of July. It was summoned for the purpose of voting money to maintain the troops who were to be employed in suppressing the conventicles or field meetings of the Presbyterians; and a supply of thirty thousand pounds a year, for five years, was granted. The Opposition, led by Hamilton, could muster only thirty-nine votes, while the supporters of the Government numbered one hundred, including, of course, all the Bishops. Among the thirty-nine was Fletcher, who thus, from the outset of his public life, took his stand against the arbitrary system on which Scotland was governed until the Revolution. During this short session an incident took place which was very characteristic of Fletcher. The Estates had ordered that none but members were to be admitted to the Parliament House. Fletcher’s brother Henry, however, had managed to slip in. He was discovered, fined, and sent to the Tolbooth. So next day Andrew Fletcher ‘pitched on little William Tolemache as no member,’ as Lord Fountainhall puts it. On this Lauderdale was forced to declare that he was one of his servants, whom he was entitled to bring into the House. This is the first instance of that hot, pertinacious spirit which Fletcher so often displayed on the floor of the Parliament House; nor, trifling as the incident was, must it be forgotten that it required some courage to face Lauderdale, whose easygoing, plausible manner concealed a most vindictive spirit.
