M^r. Charles Darwin | Dear Sir

I have sent you a dozen of the large beetles which I told you of having seen in Chiloé, & which I believe are not in your collection; I found them in the crutch of átenihue tree, thirty feet from the ground in a nest of moss; I was led to the spot by following one of them morning & evening for several days, & always lost sight of it near this tree, which is situated about 200y^ds. from the church of Caucague, at last on the morning of the 15^th. curr^t. I with some dificulty ascended the tree & found them in the crutch, as above refer’d. I killed them with heat in an earthen dish & put them in the box when cold.

Feb^y. 20^th. at 11^h. 33^m. A.M. the Island of Caucague was Visited by an earthquaqe, which lasted seven minutes & forty seconds, it was not preceeded nor folowed by any subteraneous noise, the motion was horizontal from N.E. to S.W. slow & not strong, like the motion of a vessel in y^e long gentle swell of the ocean, the trees were violently agitated, but very few were thrown down, the swell in the channel did not strike the shore more than two feet perpendicular height.

There is a block of fine grained granite, on the beach of Aucar, opposite the N.W. point of Caucague, length N. & S. 18f^t. 3in^s. hieght on the E. side 9f^t. 4in^s. circumference four feet above ground 54f^t. 10in^s.—the cross measure over the middle of the stone from ground to ground was N. & S. 31f^t. 3in. E. & W. 26f^t. 1in. there is a block of coarse grained granite on the point lobos of Caucahue, its elevation estimated 200 feet above the level of the sea—length 9 feet perpendicular thicknes 4f^t. Horiz^l. thicknes 6f^t. I have seen many blocks of granite on the surface of the ground in diffrent places & also on the beach, but never embeded in the cliffs, except in one instance, in point Chouan estimated length N. & S. 7 feet perp^r. thicknes 4f^t. Hor^l. thicknes unknown, estim^d. hieght above the sea 80 feet—

I have heard of a block of granite situated in the Potrero of the Reycaquines, 8 miles west of Lluco, said to be the largest stone on chiloe, a man on its top can over look the woods to a great distance, I know not, whether that circumstance is owing to the hieght of the stone, or to the elevation of ground it stands on. I expect the potrero will be surveyed shortly, should I be sent on the commision, I will measure the stone & send you the contents.²

I start this morning for Caylin & will return surveying the Indians lands as far as Rouca which will occupy me two months. If I should see any thing which I consider useful, I will send you word next Summer— M^r. Robert Burr will forward this & the Box. | Cha^s. D Douglas *S 2
