It's Elementary

Sherlock Holmes and Dr Watson went on a camping trip.  After a good
meal and a bottle of wine they lay down for the night, and went to sleep.

Some hours later, Holmes awoke and nudged his faithful friend awake.
"Watson, look up at the sky and tell me what you see."  

Watson replied, "I see millions and millions of stars."

"What does that tell you?" Holmes questioned.

Watson pondered for a minute.  "Astronomically, it tells me that
there are millions of galaxies and potentially billions of planets.
Astrologically, I observe that Saturn is in Leo.  Horologically, I deduce
that the time is approximately a quarter past three. Theologically, I can
see that God is all powerful and that we are small and insignificant.
Meteorologically, I suspect that we will have a beautiful day tomorrow.
What does it tell you?" 

Holmes was silent for a minute, then spoke.

"Watson, someone has stolen our tent."
