I’ve found the actual street number of the quarry owned by Lovecraft…

DeMagistris, Mariano, Providence Crushed Stone & Sand Co., 647 Manton Ave.

“647” had eluded me in my post on Lovecraft’s Quarry, but doesn’t change my identification of the site…

Having the number may perhaps help someone locate a photo of the place, which was effectively ‘on the other side of Federal Hill’ from Lovecraft.

In the meantime here’s a postcard that’s Rhode Island but not of Lovecraft’s quarry, though it pretty much sums up how I imagine it would have looked…

Also found by chance, the ‘Colour out of Westerly’…
