We studied the distribution of dust clouds around the central engine of NGC1068 based on shifted-and-added 8.8 - 12.3 micron (MIR) multi-filter images and3.0 - 3.9 micron (L-band) spectra obtained with the Subaru Telescope. In aregion of 100 pc (1.4") around the central peak, we successfully constructedmaps of color temperatures and emissivities of the MIR and L-band continua aswell as the 9.7 micron and 3.4 micron dust features with spatial resolutions of26 pc (0.37") in the MIR and 22 pc (0.3") in the L-band. Our main results are:1) color temperature of the MIR continuum scatters around the thermalequilibrium temperature with the central engine as the heat source while thatof the L-band continuum is higher and independent upon distance from thecentral engine; 2) the peak of the 9.7 micron silicate absorption feature isshifted to a longer wavelength at some locations; 3) the ratio of the opticaldepths of the dust features is different from the Galactic values and showcomplicated spatial distribution; and 4) there is a pie shaped warm dust cloudas an enhancement in the emissivity of the MIR continuum extending about 50 pcto the north from the central engine. We speculate that material falls into thecentral engine through this cloud.Comment: 26 pages, 9 figures. Accepted for publication on Ap
