The exciting feature of recent times is the inflow of new experimental data. Fits to the $\pi, \r$ and f meson resonances found by the VES collaboration, along with those of the PDG 1998 compilation are reported using a non-linear model for Regge trajectories. There are only five parameters including the pion mass and the states come out as Regge -type excitations of the pion. Total number of mesons fitted are 23 and the fit is good to $\sim$ 3% for 18 of them and $\sim$ 9% for others.
