Abstract

The Agricultural Experiment Station Bulletin Illustrations consist of photographs and other illustrations reproduced in Station Bulletins published from the mid-1920s to early 1940s. The subjects are representative of the various agricultural research projects conducted in Corvallis and at Branch Stations throughout Oregon.

Images from this collection have been digitized and are available in Oregon Digital.

Scope and Content Notes

The Agricultural Experiment Station Bulletin Illustrations consist of photographs and other illustrations published in the Station Bulletin series. These illustrations were used in 129 Station Bulletins (with numbers 214-398) published between 1925 and 1941. Not all of the Bulletins published during this time period are represented.

Subjects of the illustrations are representative of the various agricultural research projects conducted in Corvallis and at Branch Stations throughout Oregon during this time period. Notable topics are horticulture, especially fruits, berries, and nuts; dairy husbandry and production; forage crops such as hay alfafa, and oats; cattle and sheep raising and marketing; poultry; speciality crops such as hops and flax; soils and irrigation; and plant diseases and insect pests. In some cases, individual farms or processing facilities are identified.

Of special note are photographs of Asian pears and pear trees taken by Frank Charles Reimer during a trip to China and published in Station Bulletin 214 in 1925.

The bulk of the photographs are photographic prints; the collection includes 10 film negatives and 7 nitrate negatives. Other illustrations are included for most bulletins including charts, graphs, diagrams, equipment drawings, and maps.

Images from this collection have been digitized and are available in Oregon Digital.

Biographical / Historical Notes

The Oregon Agricultural Experiment Station was established under the provisions of the federal Hatch Act of 1887, which provided grants of $15,000 to each U.S. state and territory for experimentation in the "principles and applications of agricultural science." Agricultural experimentation began at Oregon Agricultural College in 1888 under Edgar Grimm, the Station's first director, and in 1889 state legislation was approved formally establishing the Experiment Station. That year, the Station published its first bulletin and the college farm was increased from 35 acres to 155 acres.

In 1901 the first Branch Station was established at Union, in northeast Oregon, to address issues pertaining to the agriculture in that part of the state. Over the next few years, Branch Stations were established throughout Oregon, at Hermiston and Moro (1909); Harney and Talent (1911); Hood River (1912); and Astoria (1913). Prior to World War II, stations were established at Pendleton (1927); Medford (1931); Squaw Butte (1935); Klamath Falls (1937); and Oregon City (1939).

Major achievements of the Station's first 50 years included a successful way to remove spray residues from fruit; introduction of new grain varieties; new methods for storing and marketing Oregon pears; control of various livestock diseases; development of the modern maraschino cherry; and poultry breeding for egg production.
