ND FAMILY--FROM THE PHOTOGRAPH OF
MESSRS. BYRNE, RICHMOND.]

The marriage of his Royal Highness to Princess Alexandra of Denmark,
on March 10, 1863, was one of the happiest events within the memory of
this generation. It tended visibly, of course, to raise and confirm
his position as leader of English society, and as the active dispenser
of that encouragement which royalty can bestow on commendable public
objects. Charity, education, science, art, music, industry,
agriculture, and local improvements are in no small measure advanced
by this patronage. The Prince of Wales may not be so learned in some
of these matters as his accomplished father, but he has taken as much
trouble to assist the endless labors of the immediate agents, in doing
which he has shown good judgment and discretion, and a considerable
degree of business talent--notably, in the British preparations for
the Paris Exhibition of 1867, the Indian and Colonial Exhibition of
1886 in London, and the organization of the Imperial Institute. The
last-named institution and the Royal College of Music will be
permanent memorials of the directing energy of the Prince of Wales.

These are but a few examples or slight indications of the work he has
actually done for us all. It is unnecessary to mention the incidental
salutary influences of his visits to Canada and to India, which have
left an abiding favorable impression of English royalty in those
provinces of the empire. Nor can it be requisite to observe the manner
in which the prince's country estate and mansion at Sandringham, with
his care of agricultural improvement, of stock breeding, studs, and
other rural concerns, has set an example to landowners, the value of
which is already felt. We refrain upon this occasion from speaking of
the Princess of Wales, or of the sons and daughters, whose lives, we
trust, will be always good and happy. It is on the personal merits and
services of the head of their illustrious house, with reference only
to public interests, that we have thought it needful to dwell, in view
of the fiftieth birthday of his Royal Highness; and very heartily to
wish him, in homely English phrase, "Many happy returns of the
day!"--_Illustrated London News._
