Btw, Bateman was somehow mistaken, the passage beneath the rocking stone is nowhere near big enough to pass animals through, yeah at the front of the stone there's a rather large opening but it narrows down to almost nothing at the back, no way could you safely pass a baby through unless you had octopuss arms and a couldn't care less attitude to your young uns.
Ok prod a piglet with a pointy stick and it would make it through i admit but it's not practical to do so on any scale.
My Jack Russel could do it at a squeeze if i stood the other side with a nice bit of meat to temp her.

"Nearly a quarter of a mile west of Row-tor is another assemblage of large rocks, forming a similar kind of hill, called Bradley-tor, after a former owner of the property on which they stand; on the upper part is a rocking stone 32 feet in circumference, and of orbicular shape, and raised above the ground by 2 stones having a passage between them. This conforms in every aspect to the Tolmens or rock idols described in Borlase's 'Antiquities of Cornwall' in which part of England there are many examples of this form rocking-stones...."
