Well I know that I haven't been completely into these discussions, but I will offer my input on this chapter
One thing I noticed while reading it last night is there is a lot of mentions of food and drink. And it's not just the normal food and drink, but it is food and drink that stands out apart from other mentions of food in the book (quite like Lembas). Like for example there is most notably the elven bread (which in the beginning Frodo has to devote his complete attention to it to enjoy), the
Golden Perch brew ("Short cuts make delays, but inns make longer ones", very good quote), The elven drink ("...pale golden in colour: it had the scent of a honey made of many flowers..."), and of course the Mushrooms in the basket at the end from Farmer Maggot, which end the problems Frodo had with Maggot once and for all.
And then another part that stood out to me is the entire part (which is also mentioned above), where Maggot tells Frodo that he should have never associated himself with the "Hobbiton folk". Basically telling him that him moving there is the source of all of his problems. And even though he is partly right, this stood out because to me it's a very hobbitish response. He is not looking that his problems could have came from the world around them, he is saying that the problems came from the hobbits that he didn't know very much, again reinforcing the fact that the hobbits tend to mistrust strangers.
And this question may seem competely random, but why does Tolkien use the word "waggon" instead of "wagon"? I just kind of find it interesting, because this is the first and only place I have ever seen the word "waggon".
