Pickering's largest and most successful grist mill, ( flour mill) was opened close by on Kingston Rd at the present site of Moodies Motel. In order to provide the necessary water pressure to operate the five water wheels at the mill, a one-mile-long mill race or canal was built. This canal began at Duffin's creek east of Riverside Drive and continued to its junction with Elizabeth Street.
To get the final coordinates, how many feet long was the sluice that flowed into the mill. This number is A.
Take A and divide by 4. Add 8 to this number to get BBB
( A / 4) +8 = BBB
Next, what year did John L Spink open his grist mill? Use the last two digits in the number to get C. Take C and multiply by 3. Add 37 to get DDD
(C X 3) + 37 = DDD.
The final cache is located at N 43 51.BBB W 79 04.DDD
