  We study the transport through a quantum dot, in the Kondo Coulomb blockade
valley, embedded in a mesoscopic device with finite wires. The quantization of
states in the circuit that hosts the quantum dot gives rise to finite size
effects. These effects make the conductance sensitive to the ratio of the Kondo
screening length to the wires length and provide a way of measuring the Kondo
cloud. We present results obtained with the numerical renormalization group for
a wide range of physically accessible parameters.
