Based on experimental observations we propose the small-polaron hopping model to interpret the behavior of the resistivity of PrBa2Cu 3\_xGaxO7 y system with x= 0.00-0.60 in a wide temperature range ( 14-290 K), reported by other workers. Using percolation arguments we evaluate the maximum hopping d
