Finally got to hunt an old home site yesterday evening. The elderly gentleman had given me permission to hunt all his property and he had kindly given me a little history of the different home site that were on the property. I listen intently to every word to obtain as much information as possible of each locations. One of the sites was a home assembled using wooden pegs. He proceeded to explain that he tore the home down and burned the balance then proceeded to get a dozer to grade the property and fill in with dirt. He did explain that anything there would be over a foot deep and he was correct, I couldn’t find anything that would date the property to the early 1800’s.
The second site I hit yesterday and even though I didn’t find any nice relics I had a lot of fun just hunting. Moving around in the area I noticed a section where the Equinox would give many false high tones. Knowing this usually meant iron I opened up the screen and every sweep revealed multiply low tone iron signals. After a while I decided to start digging these low tones that gave an ID of -3 and found my answer, cut nails. Wow, that means I’m on an old site, yes, excitement overwhelmed me for a few minutes.
Noticed the Ole man walking up the field to where I was I waited for his arrival. Knowing he would have more to say and the very first thing out of his mouth was, “have you dug any cut nails yet?” My answer, yes sir and handed him one and the story unfolds more detail of the site. He said when he was a child there was only a few foundation rocks left of this house, no wood but only the rock foundation. That was 80 years ago and he estimated the site may have been 200 years old. At that point I got extremely excited at what might be here until the very next statement from the gentleman. “Mark, I had the site leveled many years ago.” “But I pushed all the dirt to level the lot in one direction and I would guess your best bet of finding anything would be along the banks of the hill.” Well, yet another let down, a site dozed, that destroys the originality of where and what could have been found. But I’ll continue to hunt while I can and digging cuts nails is still fun.
"Nails provide one of the best clues to help determine the age of historic buildings, especially those constructed during the nineteenth century, when nail-making technology advanced rapidly. Until the last decade of the 1700s and the early 1800s, hand-wrought nails typically fastened the sheathing and roof boards on building frames. These nails were made one by one by a blacksmith or nailor from square iron rod. After heating the rod in a forge, the nailor would hammer all four sides of the softened end to form a point. The pointed nail rod was reheated and cut off. Then the nail maker would insert the hot nail into a hole in a nail header or anvil and form a head with several glancing blows of the hammer. The most common shape was the rosehead; however, broad "butterfly" heads and narrow L-heads also were crafted. L-head nails were popular for finish work, trim boards, and flooring.
Between the 1790s and the early 1800s, various machines were invented in the United States for making nails from bars of iron. The earliest machines sheared nails off the iron bar like a guillotine. The taper of the shank was produced by wiggling the bar from side to side with every stroke. These are known as type A cut nails. At first, the heads were typically made by hand as before, but soon separate mechanical nail heading machines were developed that pounded a head on the end of each nail. This type of nail was made until the 1820s.
By the 1810s, however, a more effective design for a nail making machine was developed; it flipped the iron bar over after each stroke. With the cutter set at an angle, every nail was sheared off to a taper. With the resulting nails thus all oriented in the same direction, it became possible for the same machine to automatically grip each nail and form a head in a continuous mechanical operation. Nails made by this method are known as type B nails.
Cutting the nails leaves a small burr along the edge as the metal is sheared. By carefully examining the edges for evidence of these burrs, it is possible to distinguish between the earlier type A nails and the later type B nails. Type A nails have burrs on the diagonally opposite edges, while the type B nails have both burrs on the same side because the metal was flipped for each stroke.
This kind of evidence can be used to establish the approximate period of construction or alteration of a building. Type B cut nails continued to be the most common through most of the greater part of the nineteenth century.
With the rapid development of the Bessemer process for producing inexpensive soft steel during the 1880s, however, the popularity of using iron for nail making quickly waned. By 1886, 10 percent of the nails produced in the United States were made of soft steel wire. Within six years, more steel-wire nails were being produced than iron-cut nails. By 1913, 90 percent were wire nails. Cut nails are still made today, however, with the type B method. These are commonly used for fastening hardwood flooring and for various other specialty uses."
Steve has listed many valuable USGS books, publications and other items for you to obtain or find in a library so you can see where gold was found..This makes decisions so much easier about areas you might be interested in.. One bit of advice that I learned from these publications and I have had most of them for years for I studied the ones I was interested in carefully ... I soon realized these old time geologists that traveled to these sites many times on horseback is this, they were very thorough in their investigations... The language they used to describe what they saw made me realize this was the info I needed to successfully use a Detector in that area.. These words that you are looking for are Coarse, Shotty, Rough, Nuggety Heavy Etc..These are areas that contain gold that can easily be found by a persistent hunter.. Good Luck, Good Hunting and Never give up.....
I was reading a news story today and was shocked at what they use for Chaff. Small bits of aluminum foil are sprayed out over a large area to confuse radar. The Australian military shot out a massive amount of chaff over Sydney to hide a training exercise from foreign Radar.
I would be greatly annoyed if chaff was deployed over any area where I detect.
If you checked the weather radars for Sydney yesterday you could have been forgiven for expecting a patch of heavy rain just north of the city. But if you poked your head out the window, it was nothing but blue skies.
All that action on the radar picture above is chaff, Sydney had clear skies on the day of the exercise.
What appeared to be an ominous storm cloud rolling across the weather radar was actually a military aircraft tactic used to hide activity and confuse the enemy.
Known as chaff, it’s a radar countermeasure in which aircraft or other military targets spread a cloud of small, thin pieces of aluminium, metallised glass fibre or plastic. The radar-jamming material either appears as a cluster of targets on radar screens or overwhelms the screen with hundreds of returns, or “false echoes”.
And you think canslaw is bad! 🙂
