The very worst location in the world, as I have remarked, is this windy promontory past which the grey tides race, but so long as a city can dramatise itself, one situation will do as well as another in which to render itself immortal.

The bay of San Francisco with its contingencies is one of the most interesting of inland yachting waters, full of adventurous weather. It is possible to sail in one general direction from Alviso to the city of Sacramento, a hundred and fifty miles, and that without attempting the thousand miles of estuary and slough through which the waters slink and wind.

At this season of the year the river is pushed backward by the tide a matter of ten miles or more above Sacramento City: on the San Joaquin it is felt as far as Crow's Landing. At Antioch it begins to be saltish, and down through Suisun and Carquinez the river-water fights its way as far as San Pablo before its identity is wholly lost. At flood-times it may be traced, a yellowish, turgid streak, as far as Alcatraz. This is the islet of the albatross which lies south of the tide race, as Tiburon is on the north, fragments all of them of that salt-rimed ledge outside the gate where hoarse sea-lions play, and brother to the castellated cloud far along on the sea's horizon, the very capital of the kingdom of the Little Duck.

MILL VALLEY, AND BACKWATER OF SAN FRANCISCO BAY

The Faralone Light is the last dropped astern by the Island steamships sagging south to the equator; it is also the sea-birds' city of refuge. This is the great murre rookery of the west coast, and formerly thousands of dozens of eggs were regularly taken from the Faralones to the San Francisco market; but since the islands became a Government station the murres have no enemy but the pirates of the air. In clefts and ledges close against the wall-sided cliffs they defend their shallow nests against the sheering gulls, or, hard beset, will push their single, new-hatched nestling into the friendlier sea, darting to break its fall with incredible swiftness, for a swimming gait is one of the things that come out of the shell with the native-born at the Faralones. On the same shelving rocks puffins rear their ratty young in burrows or under sheltering boulders, and the ashy petrel, the "little Peter" of the sea, walking by night before the storm, comes ashore here to hide his seldom nest. On the south Faralone the fierce cormorant builds her house of painted weed, which often the gulls steal from her as fast as she brings it ashore, for the gulls are the grafters of the sea-birds' city. This particular variety, known as the western gull, neither fishes for himself nor forages for building material. He feeds on the eggs and nestlings of his neighbours, or waits to snatch the day's catch from the beak that brought it up from the sea. He has the virtue of all predatory classes, an exemplary domesticity. His nest is soft and clean, his nestlings handsome. The western gull is often found marauding far up the estuary of Sacramento, but it is his congener, the herring gull, who follows the long white wake the ferries make ploughing the windy bay; or, distinguished among the silent shore birds for multitude and clamour, scavenges its reedy borders.

Except for the promontories north and south, and the bold front of the Berkeley Hills opposing the Gate, the inland borders of the bay are flat tide-lands and sea-smelling lagunas. Stilts, avocets, herons, all the waders that haunt this coast or visit it in their seasonal flights, may be seen stalking the shallows for minnows, or where the marsh grass reddens, poised like some strange tide-land blossom, lifted on two slender stems. Low over them any clear day may be seen the grey old marsh hawk sailing, or the "duck hawk," the peregrine of falconry, following fiercely in the wake of the migrating hordes of water-fowl. All about Alviso the guttural cry of the black-crowned night-heron sounds eerily above the marshes, along with the peculiar "pumping" love-song of the bittern.

For some reason the air of the marshes is friendly to the mistletoe infesting the oaks and sycamores which stand back from the tide-line; but the marshes themselves are treeless. They have their own sorts of growth, cane and cat-tails and tule, goosefoot, samphire, and the tasselled sedges. This samphire of Shakespeare, l'herbe de Saint Pierre of the Normandy Marshes, is the glory of the Franciscan tide-lands; miles of it, barely above the level of the slow-moving water, spread a magic carpet of blending crimsons, purples, and bronzes. Under the creeping mists and subject to the changes of the water, beaten to gold and copper under the sun, it redeems the flat lines of the landscape with a touch of Oriental splendour.

For it is a flat kingdom, that of the Little Duck—the hills hanging remotely on the horizon, the few trees and scattered hugging the low shore of the sloughs as the shipwrecked cling to their rafts, desperate of rescue. The rich web of the samphire, the shifting colour of the water, faintly reminiscent of Venice, borrow another foreign touch from the names under which the borders recommended themselves to attention:—Sausalito, "little willows," Tiburon, Corta Madero, San Quentin, San Raphael. Approached from the water, these names, with the exception of San Quentin, do no more than stir the imagination. San Quentin, on one of those courtesy islands newly rescued from the primordial mud, shows itself uncompromisingly for what it is, one of those places for the sequestration of public offenders, which is itself such an offence to our common humanity—to say nothing of our common sense. Free tides, free sails go by, and long, untrammelled lines of birds; south above the blue bay and bluer shore, the ethereal blue dome of Diablo lifts into the free air. Across the upper end of San Pablo Bay, which is really the north arm of the bay of San Francisco extending inland, Mare Island lies so low on the water that if it had not been made a naval reserve station it is difficult to know to what other use it could be put. One expects to have the land dip and swing from under like the ship's deck. It is in line with the guns which lie beside the Gate like watchful, muzzle-pointed dogs, and commands the whole upper bay and the opposing bluffs of Contra Costa in a manner highly commendable to those curious persons whose chief excitement lies in anticipating an Asiatic invasion. Nevertheless, along with the bastions of San Quentin it strikes, somehow, the note of human distrust amid all this charm of light and line and elusive colour, as if suddenly one should discover the tip of a barbed tail under the skirt of some seductive stranger.
