h India is celebrated. Then we have a
jacquard loom worked by manual power, and the large embroidering-machine
of Lemaire of Naude, and the diamond-workers of Amsterdam working in a
glazed room which affords an excellent opportunity of seeing them without
subjecting them to the annoyance of meddlesome visitors.

As if for contrast, the Galerie d'Iena at the other end of the building is
replete with the most gorgeous productions of India and France. One half
of it is occupied by the Indian collection of the prince of Wales and the
exhibits of the East and West Indian colonies of Great Britain, just
described--the other half by a pavilion, the recesses of which show the
Gobelin tapestries, while the richest productions of Sevres are placed in
profusion around it and occupy pedestals and niches wherever they could be
properly placed. The combined effect of the individual richness of the
things themselves and their lavish profusion constitutes this gallery the
gem of the Exhibition. As if the thousands of gems on the gold and silver
vessels and richly-mounted weapons and shields of the prince of Wales's
collection were not rich enough, a kiosque has been erected in which the
state jewels of France are displayed on velvet cushions, conspicuous among
them being the "Pitt Diamond," the history of which is too well known to
need repetition here.

The models, plans and raised maps of the hydraulic works of Holland are
ever wonderful. They are principally the same that were exhibited in the
Main Building at the Centennial, but there are some additional ones. All
other drainage enterprises sink into insignificance beside those of
Holland. Since 1440 they have gradually extended until they include an
area of 223,062 acres drained by mechanical means. The drainage of the
Haarlem Meer (45,230 acres), which was the last large work completed, is
abundantly illustrated here, both as to the canalization and the engines,
the latter of which are among the largest in the world. The engines are
three in number, and the cylinders of the annular kind, the outer ones
twelve feet in diameter, and each engine lifting 66 tons of water at a
stroke: in emergencies each is capable of lifting 109 tons of water at a
stroke to a height of 10 feet at a cost of 2-1/4 pounds of coal per
horse-power per hour--much cheaper than oats: 75,000,000 pounds are raised
1 foot high by a bushel of coal. The next great work is the drainage of
the southern lobe of the
