We have performed an optical spectroscopic and photometric search for youngstellar objects associated with the molecular cloud Lynds 1340, and examinedthe structure of the cloud by constructing an extinction map, based on SDSSdata. The new extinction map suggests a shallow, strongly fragmented cloud,having a mass of some 3700~Msun. Longslit spectroscopic observations of thebrightest stars over the area of L1340 revealed that the most massive starassociated with L1340 is a B4 type, about 5 solar mass star. The newspectroscopic and photometric data of the intermediate mass members led to arevised distance of 825 (+110 /-80) pc, and revealed seven members of the youngstellar population with M > 2 solar masses. Our search for H alpha emissionline stars, conducted with the Wide Field Grism Spectrograph 2 on the 2.2-metertelescope of the University of Hawaii and covering a 30 arcmin x 40 arcminarea, resulted in the detection of 75 candidate low-mass pre-main sequencestars, 58 of which are new. We constructed spectral energy distributions of ourtarget stars, based on SDSS, 2MASS, Spitzer, and WISE photometric data, derivedtheir spectral types, extinctions, and luminosities from BVRIJ fluxes,estimated masses by means of pre-main sequence evolutionary models, andexamined the disk properties utilizing the 2-24 micron interval of the spectralenergy distribution. We measured the equivalent width of the H alpha lines andderived accretion rates. The optically selected sample of pre-main sequencestars has a median effective temperature of 3970 K, stellar mass 0.7 Msun, andaccretion rate of 7.6 10^{-9} Msun/yr.
