Design and Construction
The newly formed Board on the Design of Ships began the design process for Cruiser Number 6 in 1889. For main armament, the board chose 8 inches (200 mm) guns, though the number and arrangement of these weapons, as well as the armor scheme, was heavily debated. On 8 April 1890, the Navy solicited bids but found only one bidder, the Union Iron Works in San Francisco, California. The contract specified a cost of $1,796,000, completion by 1 April 1893, and offered a bonus for early completion .
During the contract negotiations, Union Iron Works was granted permission to lengthen the vessel by 10 ft (3.0 m), at no extra cost, to accommodate the propulsion system. The contract was signed on 10 July 1890, the keel laid on 17 June 1891, and ship was launched on 5 November 1892. However, delays in the delivery of components including the new Harvey steel armor, slowed completion. The last 1-pounder gun wasn't delivered until December 1894.
Union Iron Works conducted the first round of trials on 3 November 1893; on a 68 nmi (126 km; 78 mi) run, the ship achieved a speed of 21.26 kn (39.37 km/h; 24.47 mph). Upon return to harbor, however, it was discovered that the keel had been fouled by sea grass, which required dry-docking to fix.
By 11 December, the work had been completed and she was dispatched from San Francisco to Santa Barbara for an official speed trial. Once in the harbor, heavy fog delayed the ship for four days. On the 15th, Olympia sailed into the Santa Barbara Channel, the "chosen race-track for California-built cruisers," and began a four-hour time trial. According to the navy, she had sustained an average speed of 21.67 kn (40.13 km/h; 24.94 mph), though she reached up to 22.2 kn (41.1 km/h; 25.5 mph)—both well above the contract requirement of 20 kn (37 km/h; 23 mph). While returning to San Francisco, Olympia participated in eight experiments that tested various combinations of steering a ship by rudder and propellers. The new cruiser was ultimately commissioned on 5 February 1895. For several months afterwards, she was the largest ship ever built on the western coast of the US, until surpassed by the battleship Oregon.
Scientific American compared Olympia to the similar British Eclipse-class cruisers and the Chilean Blanco Encalada and found that the American ship held a "great superiority" over the British ships. While the Eclipse's had 550 short tons (500 t) of coal, compared to Olympia's 400 short tons (360 t), the latter had nearly double the horsepower (making the ship faster), more armor, and a heavier armament on a displacement that was only 200 short tons (180 t) greater than the other.

“What but design of darkness to appall?—
If design govern in a thing so small.”
—Robert Frost (1874–1963)
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
