The permanent settlement of Utah was made possible because of the introduction of irrigation methods but the growing of crops without irrigation was successfully practiced soon after the settlement of the territory. From the existing records and from the words of many of the veterans still living it is evident that many attempts were made to grow wheat in the early 50's without irrigation. Most of these attempts failed, because they were made on irrigated lands. In 1865, however, an experiment on a much more extended scale was made.
