"...for I have just had it from Mrs. Long!"
A lot of writing guidebooks will advise you never to append any verb other than "said" to a section of dialogue, probably to avoid a stilted feel. In addition, they discourage the use of any adverbs to describe how the character is speaking. But the problem with these hard-and-fast rules is pretty easy to find - it's boring. Not just boring for the writer (quite a few things seem boring to the writer that truly are necessary), but boring for the reader, too. Constant "he said, she said, said Tom, said Jane's" in literature rarely convey the feeling behind the words, and tend to weigh down the dialogue.
Granted, it is unwise to throw out "said's" altogether, or even to major in other verbs. It's a good, old-fashioned, frank word, and it carries a lot of meeting when properly used. But sometimes it's not suited to how the character is speaking, and there is a better word to use that carries more weight and gets the point across. Of course, many times no verb is needed at all, especially when the reader knows who is speaking; then there is little call to tack on an idle "he said."
The same is true for adverbs. While it is true that being told in every scrap of dialogue that John intoned every word smartly and Isabel warbled gleefully is annoying, this is no call for throwing out all verbs and adverbs. It merely means that writers have to be careful that they do not abuse these things, but use them to the best advantage in their prose. It's very difficult, and even a little silly, to make any set, immovable laws about writing technique, because there are always exceptions and variations to every rule.
