Voltaire was prevented by age and decrepitude from appearing in public; but he heard of her arrival, and took the opportunity of addressing a letter to the Academy renewing his attack on Shakespeare. She was present when this letter (intended as a crushing response to her essay) was read. The meeting over, the president observed to her apologetically, “I fear, Madam, you must be annoyed at what you have just heard.” She at once answered, “I, sir! Not at all. I am not one of M. Voltaire’s friends!”

She had already named as her heir her nephew Matthew Robinson (the younger of the two sons of her third brother Morris), who assumed, by royal licence, the surname and arms of Montagu. In young Matthew, now a boy of fourteen, her hopes and affections were accordingly centred. His education was her first care. She sent him to Harrow, where he did dwell. In the holidays, she had him taught to ride and to dance, the latter exercise being essential, in her opinion, for giving young people a graceful deportment. She was indeed shocked at observing, on one of her later visits to Tunbridge Wells, that owing to there being a camp hard by at Coxheath, young ladies had adopted a military air, strutting about with their arms akimbo, humming marches, and refusing to figure in the courtly minuet.

When he was seventeen, Matthew Montagu was entered at Trinity College, Cambridge. Here again, without doing anything remarkable, he acquitted himself creditably, and never got into a single scrape. While he was thus progressing, his aunt was preparing to leave her residence in Hill Street, and move into a far finer mansion which she had purchased in Portman Square. This edifice, considerably altered and modernised, fills up the north-west angle of the square. It is conspicuous for its size, and the spacious enclosure surrounding it. Much building and decorating had to be got through before the fortunate owner could migrate thither. In the following extract from a letter written at the time, she proves herself a sharp woman of business:

“My new house is almost ready. I propose to move all my furniture from Hill Street thither, and to let my house unfurnished till a good purchaser offers. Then, should I get a bad tenant, I can seize his goods for rent; and such security becomes necessary in these extravagant times.”

Meantime, extensive improvements were being carried on at Sandleford. Within the house, various Gothicisms, in imitation of Strawberry Hill, were contrived. Without, what with widening of streams, levelling of mounds, planting in and planting out, our good lady’s purse-strings were kept perpetually untied. Yet she managed to keep well within her income. The celebrated landscape-gardener, “Capability” Brown, superintended matters.

“He adapts his scheme,” she says, “to the character of the place and my purse. We shall not erect temples to heathen gods, build proud bridges over humble rivulets, or do any of the marvellous things suggested by caprice, and indulged by the wantonness of wealth.”

The winter of 1782 found Mrs. Montagu established at her palace, for so her foreign friends called it, in Portman Square. Everything about it delighted her—the healthy open situation, the space and the magnificence. We hear of one room with pillars of old Italian green marble, and a ceiling painted by Angelica Kauffmann. At a later date, she further adorned it with those wondrous feather hangings, to form which, feathers were sought from every quarter, all kinds being acceptable, from the flaring plumage of the peacock and the parrot to the dingier garb of our native birds. It was with reference to this feathering of her London nest that the poet Cowper wrote:

“The birds put off their every hue, To dress a room for Montagu.”

When Matthew Montagu left Cambridge, there was a talk of his making the grand tour. His aunt, however, decided that the atmosphere of home was less likely to be corrupting. The scheme was therefore abandoned, and he was sent forth instead into London society. The impression he made was such as to satisfy her. She was of course anxious that, if he did marry, he should exercise judgment in his choice. When therefore he fixed his affections on a charming girl with fifty thousand pounds, she could raise no objections. He entered Parliament as member for Bossiney,[45] and in 1787 he seconded the Address to the Throne in a maiden speech which appears to have attracted some attention; members of both Houses called to congratulate his aunt upon his successful start in public life: “indeed, for several mornings,” says she, “I had a levée like a Minister.”

In process of time a grand-nephew made his appearance, and then Mrs. Montagu’s cup of joy seemed to be full. From this point her life flowed smoothly onward to its close. Death had made sad havoc among those who had assembled around her once, yet the gaps were quickly filled. She entertained more splendidly than ever. Her parties differed from the old gatherings in Hill Street. Royalty honored her with its presence. Titles, stars, and decorations abounded: she herself had never been more sparkling: yet the witty aroma being more diffused, smelt fainter. While welcoming the rich, she did not forget the poor. Every May Day, the courtyard before her house was thronged by a multitude of chimney-sweeps, with faces washed for the occasion, and for these a banquet of roast beef and plum pudding was provided.
