TIDE TABLE.

(Corrected 1869.)

The Tides given in the Calendar pages are for the Port of Boston.

The following table contains the difference between the time of High Water at Boston and several other places in Massachusetts Bay. The tides of places outside of Massachusetts Bay cannot be referred with any accuracy to the tides of Boston, as the difference in time varies from day to day.

The sign - prefixed to the minutes in the table, denotes that they must be subtracted from the Boston time.

When this article meets the eye of our readers the Pacific Railroad will have become an old story, and to cross the continent of America in seven days will be a thing so common, as to be little thought of. Yet the opening of this road in May, 1869, was an event of great moment. Other roads will follow, and the great interior of the continent, with its vast mineral and agricultural resources, will be thrown open to the thronging hosts of Europe, Asia, and America, and the wilderness will become a garden. Our public lands still unsold are of vast extent. The building of these roads will bring millions of acres of them into the market, stimulating immigration from Europe, and thus building up great States, which will help pay interest and principal of the public debt.

Three great trunk roads are planned, and have been chartered and endowed with lands by Congress. These are the Northern, the Central, and the Southern. But one is as yet built. This, as our readers well know, is the Central road, running near the 41st parallel, and owned by two great corporations. The Union Pacific runs 1084 miles from Omaha, on the Missouri river, to Promontory in Utah, near the Great Salt Lake; and the Central Pacific owns from there to Sacramento, 690 miles. Sacramento is on a navigable river, and communicates both by steamers alone, and by a railroad and steamers, with San Francisco. The highest point of the road is at the summit of the Black Hills, 8240 feet above the sea, eight hundred miles from Omaha. About 150 miles farther, at Bridger's Pass, the road goes through the Rocky Mountains, 7534 feet above the sea. In California it crosses the Sierra Nevadas at the height of 7042 feet, 105 miles this side of Sacramento. The distance by this route from Boston to San Francisco is as follows:- Boston to Chicago, 1017 miles; Chicago to Omaha, 493 miles; Omaha to San Francisco, 1900 miles; in all, 3410 miles, — which is passed over in 7 days.

Some four hundred miles north of the Central road, near the 46th parallel, is to run the Northern road, chartered by Congress in 1864. This road will strike across from Lake Superior to Puget's Sound, Washington Territory, with a branch to Portland, in Oregon. When built, it will give access to upper Minnesota, Dakota, Montana, Idaho, Washington, and Oregon, thus opening a great mining and agricultural region to the settler.

The proposed Southern road was chartered by Congress in 1866, and is to run near the 35th parallel. It begins in South-west Missouri, to be connected by rail with St. Louis, Memphis, and New Orleans, and will cross the Indian Territory, Texas, New Mexico, and Arizona, to Southern California, where it will turn northward to San Francisco. Work is already begun on this road, both on the Californie side and in Missouri, and its managers confidently anticipate its early completion. Both the Northern and the Southern roads will pass through or near more fertile regions than the Central, and it is thought that all three lines are necessary to the proper development of our vast interior country, as well as for our commerce with the Pacific coast. The building of the Northern road will make the adjacent regions of British America gravitate towards our alliance, while the Southern road will unite Northern Mexico to us more closely, and all three will serve to bind together the distant members of the Great Republic.
