It is assumed that the $\ensuremath{\pi}$-baryon interactions are universal and the $K$-baryon interactions account for the large mass differences between baryons. If further all baryon spins are \textonehalf{} and $K$ spin is zero, ($\ensuremath{\Sigma}, \ensuremath{\Lambda}$) parity is even, the ($\ensuremath{\Sigma}, \ensuremath{\Lambda}$) mass difference can be neglected, and the present baryon spectrum and its isotopic spin assignments are correct, then to all orders in the $\ensuremath{\pi}$-baryon coupling constant and to the second order in the $K$-baryon coupling constants, one can obtain the essential feature of the observed mass spectrum. The magnitudes of the $K$-coupling constants that yield this mass spectrum are crudely estimated.
