I assume you want to generate numbers in the range [1,60]?
All generators including random_device produce values
is a predefined range.  To produce values in the range you
want, use uniform_int.  There's an example at
http://www.boost.org/doc/libs/1_44_0/doc/html/boost_random/tutorial.html.
It uses mt19937, but the usage with random_device is
the same.
