No need to repeat the blasphemous comments which everyone who had known Gran'pa Comstock made on that last sentence. But it is worth pointing out that the chunk of granite on which it was inscribed weighed close on five tons and was quite certainly put there with the intention, though not the conscious intention, of making sure that Gran'pa Comstock shouldn't get up from underneath it. If you want to know what a dead man's relatives really think of him, a good rough test is the weight of his tombstone.
