Evaluate the boring log provided separately and draw the stratigraphy that is represented with

proper vertical scale, and indicate the position of each split spoon sample and its N$-$value. Also determine what is the appropriate $$ value for the $3$ granular soil layers between;

depths $10$ to $25$ ft$.,$

depths $30$ to $37$ ft$.,$ and

depths $42$ to $47$ ft$..$
