We study blue horizontal branch (BHB) and RR Lyrae stars in the Rogers et al.(1993a) fields and compare their velocity and density distributions with othersurveys in the same part of the sky. Photometric data are given for 176early-type stars in the northern field. We identify fourteen BHB stars and fourpossible BHB stars, and determine the selection efficiency of the CenturySurvey, the HK Survey, and the SDSS survey for BHB stars. We give light curvesand \gamma -radial velocities for three type-ab RR Lyrae stars in the northernfield; comparison with the nearby LONEOS Survey shows that there is likely tobe an equal number of lower-amplitude type-ab RR Lyrae stars that we do notfind. There are therefore at least twice as many BHB stars as type-ab RR Lyraestars in the northern field--similar to the ratio in the solar neighborhood.The velocity distribution of the southern field shows no evidence for ananomalous thick disk that was found by Gilmore et al. (2002); the halo velocitypeaks at a slightly prograde rotational velocity but there is also asignificant retrograde halo component in this field. The velocity distributionin the northern field shows no evidence of Galactic rotation for |Z|>4 kpc anda slight prograde motion for |Z|<4 kpc. The space densities of BHB stars in thenorthern field agree with an extrapolation of the power-law distributionrecently derived by de Propris et al. (2010). For |Z|<4 kpc, however, weobserve an excess of BHB stars compared with this power-law. We conclude thatthese BHB stars mostly belong to a spatially flattened, non-rotating inner halocomponent of the Milky Way in confirmation of the Kinman et al. (2009) analysisof Century Survey BHB stars.
