VOL. 40. CLEVELAND, JUNE, 1910. NEW YORK No. 6 Commencement Bay, the Harbor of OMMENCEMENT Bay, . the harbor of Tacoma, is located at the extreme south end of Puget Sound, the largest har- bor on the north Pacific coast. To some extent, the whole of Puget Sound contributes to the harbor facil- ities of Tacoma. All of the general 'conditions of winds, tides, climate, and protection described in THe Marine Review of July, 1909, in regard to the harbor of Seattle, apply to Commence- ment Bay. The whole shore line of Puget Sound is indented with numer- ous bays and inlets, offering protec- tion and shelter at all times. At any point there is sufficient depth of water | to accommodate the largest. vessels afloat at all stages and conditions of tide. While large lumber schooners do. occasionally sail down Puget Sound, most of the sail tonnage is towed into port. The' towing charges vary from $105 for a 250-ton vessel to $325 for a 1,500-ton vessel towed: be- tween Cape Flattery. and Tacoma. The six requisites for a good harbor are summed up in: 1, protection from Storms; 2, ample depth and good anchorage; 3, size; 4, accessibility; 5, sufficient shore line for the construc- tion of the necessary docks and wharves, and 6, facilities for handling freight and for the repair of vessels. *Fifth of a series of articles describing ithe Principal harbors of the Pacific coast.

Tacoma' By Lovis P. ZIMMERMAN, Natural conditions combine to make Tacoma one of the large shipping cen- ters. Two things besides natural con- tour are necessary to bring immense quantities of staple commodities to- gether at Tacoma. There are, briefly, four cities on the northern half of Puget Sound that may be mentioned many years past, the shortest distance for. rail to meet sail was through -- With the completion of the Seattle. water grade line of the Spokane, Port- land & Seattle and the Chicago, Mil-. waukee & Puget Sound, Tacoma is competing on even terms. Nearly all. of the waters of Puget Sound are INDIANAPOLIS, PASSENGER STEAMER, PLyING BETWEEN TACOMA AND SEATTLE. as having large, deep harbors: viz., Port Townsend, Bellingham, Everett and Seattle. At the extreme south is Tacoma. 'The vital factor' in the growth of all of these towns is their railroad haul, for in all the cities on the sound, rail must meet sail to have a continued natural growth. For bordered by high, bluffy hills with' water at their very foot several hun- dred feet deep, with no place for a city except on the tops of the plat- eaus. In a few places, at the mouths of rivers flowing into the salt water, are low flat areas, shallows, or tide flats, covered with water at high tide
