They come across the grave of the boss's son too; "the girls were in Belgium last week having a look at poor Reggi's grave, and they  happened to come across your boy's". he also mention how the Graves had been well kept. He says that the Grapes of both are well kept and covers with beautiful flowers and near the graves, there are 'nice broad  paths'.
