Final answer:
Without the context of the story or details about the character 'the Warden,' an accurate answer cannot be provided as to why the counsellors were told to stop the campers from digging holes. The supplied references do not provide information relevant to the Warden's decision.
Step-by-step explanation:
The question seems to be about the motives of a character named the Warden in a narrative context. Based on the reference information provided, it is challenging to directly answer why the Warden asked the counsellors to stop the campers from digging holes without more context. None of the reference information supplied directly answers the question related to the Warden's actions. In scenarios like camping or excavation activities, the reasons for stopping digging could be varied, ranging from reaching the completion of a planned structure, such as a cellar, to situational needs like the proper arrangement of a campsite or conducting a meticulous diving mission. However, without specific information about the Warden's character or the story's circumstances, we can only speculate on the reason based on these analogous situations.
