In 1878 the roadway to Upper Astoria was completed, and the Upper Astoria post office abolished. The completion of the roadway was an event of great importance to the people of both towns, and had the effect of putting an end to the rivalry that had existed since the starting of Upper Astoria in 1849, when the customhouse was built. The towns were now in fact one, though considered locally as two separate towns. By the legislative act of 1891 the corporate limits of the town were extended so as to include upper town.

The intense rivalry between the companies operating steamers on the Portland-San Francisco route brought about the reduction of freight and passenger rates so that there was much travel between Oregon and California. As every steamer stopped several hours at Astoria the town received considerable patronage from the passengers. The Astorian speaks of the town being crowded during the stay of one of the ocean steamers. The Great Republic frequently carried a thousand passengers, and always took on a considerable part of its cargo at Astoria.

The population of Astoria in 1880 was two thousand eight hundred and three and the population of Clatsop County seven thousand two hundred and twenty-two. This increase in the number of people in the county meant much to Astoria, since the supplies for a large part of Clatsop County are taken from the city.

In 1883 the salmon industry reached its highest point. Not only were more fish canned than at any previous year but a better price than ever before was paid for the raw material, thus distributing a larger amount of money among the fishermen and cannery workers. During this season six hundred and twenty-nine thousand cases of salmon, valued at over $3,000,000, were packed on the Columbia River.

It was during this year that the fire, known locally as the "big fire," occurred. It started July 2, 1883, in the sawmill near the site now occupied by the Foard & Stokes Company and swept the entire water front from that point east to Seventeenth Street, including the large warehouse owned by the Oregon Railway and Navigation Company. The volunteer fire department worked heroically and succeeded after several hours in gaining control of the fire, though not until it had destroyed several blocks of business houses, wharves, and dwellings. The wooden streets, built on piling over the water acted as a means for carrying the fire from building to building. The loss was very heavy but the fishing season was at its height and money plentiful, so that in a short time new buildings were erected in place of those destroyed by fire.

An interesting chapter in Astoria's history is connected with the fire of 1883. During its progress a large quantity of liquor was taken from the saloons in the path of the fire and carried to places of safety only to be stolen by the rougher class of onlookers. In a short time great disorder prevailed in the vicinity of the fire and the officers were powerless to prevent the wholesale stealing of the goods taken from the stores and houses. Drinking was kept up throughout the night but after the fire was checked the scene of disorder was transferred to the lower part of town, known as "Swilltown." Here the drunken fishermen were soon relieved of their money by the denizens of this section. Later some of the fishermen threatened to burn the rest of the town in retaliation. The business men of the city fearing that this threat would be carried out organized a committee to assist the officers in preserving the peace should their aid become necessary, the mayor at the same time issuing a proclamation calling upon all saloon keepers to close their saloons each night at 12 o'clock. One saloon, owned by Riley and Ginder, two ex-policemen, refused to obey and when the officers went to arrest the proprietors they were fired upon through the barricaded doors. During the conflict three taps were sounded on the fire bell, the signal for the citizens' committee to assemble. The committee responded quickly and arrived upon the scene fully armed and ready for action. The officers in the mean time had succeeded in entering the building and had arrested Riley and Ginder who were brought before the committee. After a short deliberation they were informed that they must leave the city at once under penalty of being hanged from the city hall. The threat was sufficient and they closed their saloon and left the city. To one who knows the condition of affairs that existed in the city after the fire, and the character of the men who led the citizens' movement, it is evident that Riley and Ginder used the best of judgment in obeying promptly. After disposing of this case the committee decided to drive out the crowd of disreputable characters that lived in "Swilltown," and accordingly served notice on all such to leave town within twenty-four hours. This order, backed by a resolute set of citizens, was generally obeyed, only one man openly defying the committee. This man, an Englishman by the name of Boyle, was known as a "bad man." Nevertheless he was captured, whipped, and sent out of town. Recognizing three members of the committee he brought suit against them in the United States court for damages and secured the verdict. The amount was quickly raised by general subscription, $20 being the usual individual contribution. The citizens' committee having accomplished the purpose for which it was organized now disbanded.

Notwithstanding the steady decline in the salmon pack on the Columbia River since 1883 and the closing of many of the canneries in the city, Astoria has had a steady growth, due in a great measure to the increase in trade with the growing towns and the farming and dairy districts tributary to the city, and to the growth of the sawmill industry, which though still in its infancy here, is growing rapidly. By the close of the summer four and possibly five large mills will be in operation.

In 1890 the city had a population of six thousand one hundred and eighty-four, a very great increase over the census returns of ten years before. Two years before this the Astoria and South Coast Railroad was started and the road built from Sea Side to the middle of Young's Bay, a distance of about fifteen miles. Though this road did not enter the city for several years its building had a marked effect on Astoria. Prices for city property increased very rapidly, and during the years 1889 and 1890 a real estate boom was in progress. While considerable property changed ownership very little building was done so that when the period of activity in real estate ended the city did not contain rows of empty houses as did so many of the boom towns of Washington.

Almost from the beginning of its history Astoria has dreamed of rail connections with the East. The coming of the railroad has been regarded as the one thing needed to make Astoria the seaport of the Northwest. The Astoria and South Coast road had stopped near the center of Young's Bay. About three years later a new road that was to run up Young's River, thence through the Nehalem Valley to Portland was started. This company, after building several miles of trestle around Smith's Point and up Young's River, suspended operations owing to its inability to secure sufficient financial backing to complete the road. The Astoria and Columbia River Railroad Company was given subsidy of a million and a half in money and property and in 1898 built the present road to connect with the Northern Pacific track at Goble. The city has been greatly benefited by this road, although the long expected period of rapid growth did not accompany it, owing to the fact that Astoria has not been made a common point with other cities of the Northwest.

The population of the city in 1900 had increased to eight thousand three hundred and eighty-one. A conservative estimate places the population now at a little over ten thousand.
