Now they have four or five iron shovels.
Taking turns to dig the well.
This is all very new to these primitive people.
First, they dig a pit and then go deeper and deeper.
They found groundwater at a depth of less than four meters.
They continued to deepen it.
The diameter at the bottom of the well is about three meters.
There shouldn't be any problem providing water for over forty people.
Ma Lin was puzzled about one thing, whether the walls of the well needed to be lined with stones to prevent the earth from collapsing.
After thinking it over, he decided it should be done.
First, they deepened the bottom of the well by about a meter.
Then they hung stones down from above to build walls to protect the sides of the well and prevent it from collapsing.
Building the stone took quite some time because they needed to set up a scaffold for climbing.
After finishing, they waited for half a day for the water in the well to clear up.
