short time during their migrations, and some may remain through 
the winter. Some of these come regularly, every season ; others 
only occasionally or accidentally. Among them are various ducks 
and shore birds, but they are not usually numerous. 
Going eastward from Hamilton, in pleasant weather, the north 
road is most delightful, for it affords numerous fine views of the 
adjacent waters, which here are clear and sparkling, and have most 
surprising tints of sapphire-blue and bright turquoise-blue, chang- 
ing in the distance to deep indigo-blue or ultramarine, while in 
shallow water, nearer the shore, the color is commonly emerald-green 
or beryl-green, constantly varying in tints according to the nature of 
the bottom, the state of the sky, and the agitation of the surface. 
On occasions when a strong northerly or easterly wind is blowing, 
the north road, eastward of Hamilton, is to be avoided, because it is 
much exposed to the wind, and in many places the salt spray is 
apt to be blown across it at such times. The two other roads are 
much more sheltered from the wind, and have special attractions 
of their own. The hard, smooth road-beds, composed of the crushed 
porous limestone, are all well adapted to the cyclists, and many of 
these are constantly met on the roads, and especially on the north 
road.
