The Short periods of Delta Scuti Stars allow observational detection of the period changes expected from the stellar evolution within several tens years. For about 30 years we have kept this topic as a small systematic observational program with our 60 cm telescope. Here we publish the period variation of 18 stars . The data of 28 And are taken from R. Garrido et al. (1983), 211; the period variation rate of 4 CVn is given by M. Breger. Both of them are low amplitude variables.
