"... IRRIGON, 8 m. (297 alt., 65 pop.), on the site of old Grande Ronde Landing, a former stopping place for travelers, derives its name and sustenance from the irrigation district of which it is the center. An experiment farm nearby demonstrates the agricultural possibilities of the rich soil.

At 11.2 m. is a junction with a side road.

Right on this road to PATTERSON FERRY, 1 m. (toll for cars and five persons, $1; round trip, $1.50) connecting with US 410 at Prosser, Washington.

"... The privately owned ferry at Umatilla carried 178,576 vehicles in 1951. The high number of vehicles was due to the closure of U.S. Highway No. 730 above McNary Dam. The equipment for the ferry consisted of two unpowered steel barges that were propelled by light tug boats, the first with a capcity for 14 passenger autos, the second with a capacity for 11 passenger autos. The Paterson ferry on the Washington shore was also privately owned, and carried 146,498 vehicles in 1951. The equipment for this ferry consisted of three unpowered barges, propelled by light tug boats, with capacities for 8 and 12 passenger autos. Both ferries operated without a schedule according to traffic needs. The crossing time was about five minutes with a ten minute average wait. Both ferries went out of business when the Umatilla Bridge was built. ..."
