Analysis Key

     One day [NuA] [Adj. to "day" while Prince Chéri was out hunting [#1] ],

little rabbit [Adj. to "rabbit" that his dogs were about to kill [#2]] , [#3] threw 

itself (DO) {into his arms}. | The King caressed the little creature (DO), [#4] 

and said: [#5]

     [DO "[Adv. to "shall harm" As you have put yourself (DO) {under my 

protection}] [#6] nobody shall harm you (DO),"] | and he carried the

rabbit (DO) {to his palace}, and ordered a pretty little hutch to be made [#7]

{for it}. |

1. "Hunting" is a gerund that function as a noun used as an adverb.
2. There are, in KISS, two ways to explain "about to kill." One is to consider "about" as the equivalent of "ready," thereby making it a predicate adjective modified by the verbal (infinitive) "to kill." The second is to consider "about" as a preposition with the infinitive "to kill" as its object. In this view the prepositional phrase can be described either as adverbial to "were" or as a predicate adjective.
3. This comma bends the rule about separating a subject from its finite verb. If there were a comma after rabbit, then the two commas could be seen as setting off the adjectival clause as non-restrictive, but there is no first comma. Vredenburg, however, probably used the comma after "kill" to separate the finite verb "threw" from the immediately preceding verbal "to kill."
4. Thus comma is optional. 
5. This may be a colon instead of a comma because the direct object is in a separate paragraph.
6. Some textbooks claim that an adverbial clause at the beginning of a sentence should end with a comma, but as you can see, there is none here.
7. Some people will see "hutch" as the direct object of "ordered" and the infinitive "to be made" as an adjective to "hutch." Alternatively, "hutch" can be described as the subject of the infinitive phrase, thereby making the infinitive phrase the direct object of "ordered."
