The TRIAL of FRIENDSHIP: A Story now firft tranflated from the third volume of Contes Moraux, just published by Marmonte).

TELSON and BLANDFORD, two

NELSO

young gentlemen of fortune, were educated at the fame publick fchool, and, while they were yet chil dren, contracted a most intimate friend fhip, which became gradually stronger and more refined, in proportion as their minds opened, and their knowledge encreafed.

When their ftudies were finished, Blandford, who was of a robust confti tution, and an active and daring temper, went into the sea service, and in as ac time procured the command of a

[ocr errors]

confiderable fhip by his merit. Nelson,
who was more difpofed to reflection
and study, and was endowed with a
natural eloquence equally forcible
and graceful, was foon chofen a mem
ber of the house of commons, and im-
mediately diftinguished himself as a
fpeaker. Each of them terved their
country in his department, and each
of them was happy in the confciouf-
nefs of fuch fervice. Both were 'e-
qually examples of virtuous fortitude;
Blandford, by exerting himself againit
the enemies of his country, and the B
fury of the elements; and Nelson, by
refifting the feducements of Luxury
and Ambition.

They were animated by the fame fpirit, though divided from each other by half the globe, and mutually excited each other by their letters to do honour to Friendship by ferving their country.

nothing could induce to quit the house, neglected nothing that might footh her diftrefs, which, however, admitted but little alleviation, for the was perfuaded that the wound was mortal, A and spent both the days and nights in unavailing tears. The Bramin himfelf was confcious of the approach of death; but having conceived the highest opinion of Blandford, from feveral converfations that bad passed between them, as well as from the good offices he had done him, he called his daughter to him about an hour before he expired: Come, faid he, my dear child, and give thy dying parent a laft embrace; embrace allo thy new father; let this generous ftranger be henceforth thy guide and thy fupport; nothing can be expected in this country but fervitude and defolation; he will take you to a better, where he has fworn to confider thy honour, thy innocence, and thy li berty, as a facred and inviolable depofit in his hands. Here is the Veidam, the book that contains the religion of thy country; after having confidered it well, I would have thee learn alfo the religion of this virtuous ftranger, and chufe that for thyself which appears most conducive to the honour of God and the benefit of 'fociety.'

Blandford acquired an immenfe fortune in an expedition to the Eaft Indies, but his molt valuable prize was •Neuraly, a young Indian lady, of fuch beauty as is equally rare in all countries. Solinzeb, a Bramin, to whom D Providence, as the reward of his vir. tue, had given this daughter, an only child, recommended her to his care with his dying breath.

Neuraly was not yet quite 15; the village in which the and her father lived had been taken and pillaged by our troops; the old man was mortally wounded, and funk dying into the arms of his daughter: Juft at this moment Blandford came up, repreffed the fury of the foldiers, and rushing thro' the croud that blockaded the house, faw the Bramin leaning on his daughter, who was fcarce able to support him, trembling with confternation and terror, and bathing her dying parent with her tears: At this fight Nature, Beauty, and Love exerted all their powers upon the foul of Blandford. He foon perceived that the dying Bramin was father to the tender maid who fupported him; and driving away the foldiers, whom he reproached with having offered violence to innocence and age, he took the old man in his arms, laid him on a couch, examined his wound, and procured him the belt affittance that could be had.

Nouraly, who was a witnefs of this humanity and tender nefs, locked upon the transer as a tutelar Deity defcend ed from Heaven to fuccour and comfort her father; and Blandford, whom

While the venerable old man was yet speaking, his voice began to faulfer, the lait agony came on, he funk backward and expired. Neurally expreffed her grief by cries and tears, and embracing the dead body, continued to hold it to her breast till it became cold and livid, but at laft the violence of her paffions having quite exhausted her, she fainted, and her attendants took that opportunity to remove her from the corps.

Blandford, whom his duty foon called back to England, took his lovely ward with him, and tho' the whole voyage might be confidered as one long opportunity, though fhe was beautiful Gas an angel, and by her fimplicity rendered eafy to be feduced; and though he was in the firft vigour of life, with ftrong paffions, and deeply fmitten, yet he made not the least aftempt upon her innocence: He amyfed himself and her by teaching her a little English, by giving her fome notion of the manners of Europe, and, by degrees, removing the prejudices of her country;

When Nelson heard of his return, he fet out to meet him at the ea port

by my own, and it is I only that am degraded by my fufpicion; but let us fay no more about it: I fhall go contented, leaving Friendship the guardian of my love: But, my dear Nelfon, if I should die, may I hope that A you will take my place?" "Yes, faid Nelfon, as a father; do not prefs me farther." I will not, faid Blandford, I am fatisfied.'

and their interview was as happy as can be imagined; but when he faw Neuraly, he was touched with furprize and concern: What do you do with this child, fays he, in a severe tone; is the a captive, a flave? have you ftolen her from her parents, and done a violence to nature? Blandford replied to these questions, by relating all that had passed, and he drew fo lively a picture of the innocent fenfibility of the young Indian, that Nelfox himself was touched with tendernefs on her behalf. I'll tell you, B faid Blandford, my whole defign: I fhall place her for a time with my mother, under whofe eye the will become acquainted with our manner of life I fhall form her ingenuous and yielding mind by degrees; and if I find reafon to think that the can be happy with me I will marry her.' "I am fa- C tisfied, faid Nelfon, and you are again my friend."

:

Nouraly, to whom education was only unfolding, by a Aight culture, the powers and graces that nature had implanted in her mind, had just compleated her fixteenth year, and Bland. ford was preparing to make her his wife when his mother was unfortunately taken ill and died.

Nouraly wept for her as if fhe had been her own, and the tenderness and affiduity with which the endeavoured to footh Blandford, endeared her fill more to him. But while the marsiage was delayed on account of the mourning, he received orders to embark for a new expedition.

He went immediately to Nelfou, and pathetically lamented, not his being obliged to part with his mistress, for Nelfon would have made him afhamed of that, but his leaving her alone in a ⚫ world to which fhe was wholly a firanger." If my mother had lived, faid he, the would have been her guide and protectrefs, but the misfortune that purfues this poor orphan has ta. ken away her only fupport."- Have you then forgot, faid Nelson, that I have a fifter, and that my house is your own?' "Ah, Nelfon, faid Blandford, (looking ftedfaftly at him) if you did but know the depofit I fhall make!"

[ocr errors]

Blandford and Nourly parted with tears, but the tears of Nouraly were not those of love. A lively gratitude, and a respectful friendship were tire tender eft fentiments with which Blandford had infpired her. He had never touched that foft and refined fenfibility which is diftinguished by a dearer name than either gratitude or friendhip. This dangerous advantage was relerved for Neifen.

At these words Nelfon replied, with a smile of disdain, “A fine caufe of uneafinefs to us both, indeed! and it does us infinite honour; you are H afraid to trust me with a woman!" At this reproach Blandford blushed with confusion: Forgive my weakness, said he, Į judged of your heart

Blandford's perfon was better than Nelfon's, but his beauty, like his character, had fomething grave, robuit, and commanding. The fentiments which he had conceived for his pupil were, in their appearance, more like thofe of a father than a lover. He had care without complaisance, and kindnefs without grace; an interest that was tender, but folemn; and a defire of rendering her happy, rather than of being happy with her.

Nelfon, who had a more chearful difpofition, had alfo more fweetness in his afpect and in his language: In his eye alone there was all the eloquence of the foul: His look at once expreffed the greatest fenfibility and penetration; it seemed to reach even to the heart, and to hold a kind of fecret intelligence with it: His voice, when he spoke upon fubjects of importance, was full, fonorous, and commanding, and in familiar converfation, it had a fweetness and variety that was inexprefl.oly pleafing: He had also a manner that was neither timid nor affuming; it was a kind of native elegance and complacency peculiar to himself, and greatly fuperior to the forms of breeding, which yet he feldom neglected. This man, at the head of a nation, would have made a tyrant tremble, but in converfation he kept nobody in awe, and a flight compliment would fometimes make him blufh like a girl.

Lady Juliette Aubery, his fifter, was a widow of excellent understanding, and had one of the beft hearts in the world; but he had that kind of anxjous prudence which always prefages misfortune, and which rather incurs
