1897. 10" long:

1898. 8" long:
1899. This was sent in by a visitor who is looking to find out what it's for:
1900. 32" tall, take a look at Neatorama for more guesses on this one and a chance to win a T-shirt:
1901. This photo was shot in the basement of a house built in 1820, the idea here is to describe the purpose of this 36" x 84" x 14" hole in the floor.

1897. A Heathkit Thermo Spotter, it's a temperature indicating device for use by fishermen, a weight was attached to the cord which was then lowered into the water, when the red button was pressed the gauge would be activated, the knob with the screw was used to wind the cord back in:

1901. A tanning pit for processing animal hides in the Samuel Smith Tannery, from this site:
In the next phase of leather production, the hides were combined with oak, beech or willow bark, which would provide the tannic acid necessary in preserving and coloring the hide. Other acidic additives to this dressing included sour milk, cider pressings and ferment of rye, recipes varying according to the materials at hand, the weather and the ultimate finish desired. Bark was spread in the bottom of the tanning pit, then hides and bark alternately stacked until the pit is full. A foot of tanbark covered the pit, and the whole well trampled down and kept moistened for three months.
A full description of the process can be found at the link.
