Inscription. What is Milling?
Milling is a process of taking whole bulbs, tubers, nuts, seeds, grains or other foods from its original size to a smaller size by pounding, grinding or rolling it until it is the consistency of a meal, flour or powder.
Early Milling
From the beginning of history, man has known that grain was a great energy food. When he realized that grain could be planted and cultivated, it became possible for him to stop the wandering life and settle down in one spot. In order to get nutrition from the grain, the kernels had to be broken open. Man's teeth were the first grinding tools, but this was a very inadequate devise. By trial and error rocks were found that suited this purpose better. The rocks were saved instead of being thrown away after each use. As years passed, it was found that stones curved at both ends could keep the grain on the stone. By shaping the other stone into a roller, work could be completed much faster. This form was called a saddle stone (A). Eventually, a depression formed in the stone. Grain contained in this lower place was easier to pound and grind. From this idea, the development of the mortar and pestle evolved (B). They were used for thousands of years and many fine examples of these, as well as other grinding tools, have been found in excavations of ruins of American Indian

Why did it happen here?
Pencader Hundred was a transportation hub located midway between the Delaware River and the Chesapeake Bay. This location provided a convenient route for exportation of goods to Europe and to the Colonies to the North and South.
Cooch - Dayett Mills
Dayett Mills, pronounced locally as Die-ett, is located in Pencader hundred not far from Cooch's Bridge. It was the third mill build in the area by the Cooch family and is the only one that remains today. The mill was built in 1838 by William Cooch, Jr. it remained in the Cooch family until it was sold in 1894 to John W. Dayett. After the death of John Dayett, his wife Mary Emma Dayett sold the mill to Jonathan Irwin. William and Alberta Johnson along with Charles H. Goth purchased the mill in 1948.
The building in which the mill is housed is brick, three and one-half stories, measuring fifty feet square. It was operated by waterpower, but in 1884 was remodeled and refitted to include engines for use when water supply was insufficient.l Two fires, one in 1916 and the other in 1933, caused minor damage allowing the mill to be restored with the most notable change being to the roof. The millrace starts a little more than three-quarters of a mile north of the mill.
The mill remained in operation until the 1990's. It was sold to the State of Delaware under the control

Mills of Pencader Hundred
William McConaughy operated a sawmill in 1833 on the Christina River with the mill pond extending North to Elkton Road. The mill was in the area of Persimmon Run. Nothing of the mill remains today.
Andrew Fisher operated a gristmill just South of Chestnut Hill Road. General George Washington requested that all millstones be removed prior to the British arrival but Fisher failed to remove the stones and the British used the mill in 1777 during the Battle of Cooch's Bridge. The mill burned down in 1883 never to be rebuilt.
Four generations of the Cooch family have been millers in Pencader Hundred. Thomas Cooch, the first generation, came to Pencader in 1746 and bought a gristmill and a sawmill. Thomas Cooch Jr. was a miller until the British burned the mill in 1777. The third generation was William Cooch who built the second mill in 1792 just East of the bridge. A granary now stands over the old foundation. William Cooch died in 1837 and tow of his sons, William and Zebulon, took over the milling business until it was sold to John Dayett in 1894.
Alexander Porter operated a gristmill on Sunset Lake, just South of Dayett Mills, from 1760 to 1769 when it was purchased by David and Samuel Porter. Adam Dayett ran this mill as Valley Mill until 1888. It continued in operation by Irvin Dayett until 1932. Nothing of the mill remains today.
John Janvier built a sawmill and a gristmill in 1839 at Beck's Pond. Other owners were Porter, Kensey Johns, J. A. Kendal, Tatnall, Kyle Johns(who added a distillery), and William Kyle. The mill was torn down in 1865.
Other mills in Pencader Hundred were Crawford's Mill. Cooch Sawmill in Glasgow, clement Sawmill at Lums Pond and C&D Sawmill at Lums Pond.
How are they powered?
The breast waterwheel uses the same design as the overshot waterwheel with the buckets. The water hits the waterwheel in the middle, propelling the wheel down. This type of wheel was used when the flow of water wasn't swift enough to power an undershot wheel but the flow had enough velocity so that an overshot was not required.
The overshot waterwheel was used when there was a dependable flow of water but not a high rate of flow. An overshot waterwheel receives its water from above the wheel, and the wooden troughs are buckets. When water fills the buckets, the water's weight moves the wheel. An overshot waterwheel is the most efficient method of powering a mill when there is a limited amount of water supply because it maximizes the amount of accessible waterpower.
An undershot waterwheel was placed in such a manner so that when the headgate was open, the water flowed under the waterwheel propelling it to turn from the movement of the water striking three to four of the paddles at a time on the wheel. The undershot waterwheel was constructed with blades instead of buckets. This type of waterwheel could only be used where the flow of water was extremely high because it takes a great deal of velocity to turn a large wooden waterwheel. The undershot waterwheel was not as popular as the but was used whenever there was an ample water supply and a rapid flow.
Leading Americans in Milling Technology
Oliver Evans

Oliver Evans' mill designs became popular in the beginning of the 1800's. He developed a system of conveying grain through the milling process using one of the first concepts of an assembly line. This system was used in Cooch's Mill. He also developed a high pressure steam engine using a cooling coil. This was the forerunner of modern refrigeration systems. These inventions expedited the milling process and enabled the mills to be more profitable. Evans was an author as well as a miller and inventor. He wrote and published "The Young Millwright's & Miller's Guide" in 1795.
Benjamin Henry Latrobe
Benjamin Latrobe designed a new water power system for milling by raising the dams and placing raceways (canals) along elevation lines between the Coastal Plain and the Piedmont Plateau. He was instrumental in designing the Philadelphia Water Works, the C&D feeder canal system and the national Capitol Building.
George Washington
George Washington was not only the first President but he was also a leading organic farmer of his time. As a friend and customer of Oliver Evans, Washington advised him on how to dry and clean grain, improve crop management, keep accurate records and provided techniques for profitable marketing.
