After this occurs and once the tubes are securely in place, a hookah compressor and a low-pressure hose re-inflates them so that they form a tight grip around the floating logs. This process gives the logs more buoyancy and gives loggers easier access points to harvest them. As many tubes that are needed are used to float the logs. [4]
Floating logs down a river worked well for the most desirable pine timber, because it floated well. But hardwoods were more dense, and weren't buoyant enough to be easily driven, and some pines weren't near drivable streams. Log driving became increasingly unnecessary with the development of railroads and the use of trucks on logging roads ...
Some timbers were carefully, smoothly hewn, and there was a demand for them, especially in England, after steam sawmilling became common. On the Altamaha, for many years during the rafting era, most rafts were made up of “scab” timber, that is, logs roughly squared by broad ax for tighter assembly and for gang sawmills which could cut flat ...
In the early days, felled logs were transported using simple methods such as rivers to float tree trunks downstream to sawmills or paper mills. This practice, known as log driving or timber rafting, was the cheapest and most common. Some logs, due to high resin content, would sink and were known as deadheads.
For the most part, dolphins tend to sleep at night, but only for a couple of hours at a time. ... they look like a log floating on top of the water. Who knew that the way that an animal sleeps ...
Christmas is less than a week away, and even the night sky is spreading some holiday cheer with what could be the largest Christmas tree in the universe. On Tuesday, NASA released an image of NGC ...
Looming of the Canadian coast as seen from Rochester, New York, on April 16, 1871. Looming is the most noticeable and most often observed of these refraction phenomena. It is an abnormally large refraction of the object that increases the apparent elevation of the distant objects and sometimes allows an observer to see objects that are located below the horizon under normal conditions.
However, Dr. Kobylarz notes it can start as early as 1 p.m. for some people. What Sundowning Looks Like There’s a difference between being totally over your day and sundowning.
