What do you think this Wuthering Heights page means?.?

Catherine and Heathcliff got in trouble while they were supposed to be studying their Bible. They were banished to the kitchen, and while there Catherine is writing in her "diary", (which is really scribbling notes in the margins of various books that she has) and Heathcliff is bored and wants her to go out to the moors with him. It's a rainy afternoon, so they were going to take the dairywoman's cloak to cover themselves up to stay dry and warm outside.
