In Tables 4-13, we reproduce the observed linear polarization (p), error in estimated polarization ( $E_{\rm p}$ ), corresponding PA values ( $\theta$ ) and m (relative magnitudes) in Cols. 4, 5, 6 and 7 respectively for the stars in these clouds. These magnitudes are just a conversion from the CCD counts and therefore it is merely an indication of the relative intensity of the stars. One should also note that the magnitude scale is not necessarily same for all the clouds. The PA ( $\theta$ ) values are corrected by the $\theta$ -offset as obtained after the observation of polarimetric standard stars (please refer to Sect. 3). The field stars in a cloud can be identified through their RA and DEC co-ordinates available in Cols. 2 and 3.

We draw these polarization vectors on the respective position of the stars on the DSS map (Digital Sky Survey map of Palomar Observatory). The length of the vector is proportional to the degree of polarization. The vector line is drawn making an angle with the N-axis (towards East), which is equal to the PA values tabulated in Col. 6. However before plotting, all these $\theta$ values were corrected by the off-set ( $\rm d \theta$ ) discussed earlier for the corresponding nights of observations (please refer to Sect. 3). Also on the left-hand corner of each map we have plotted the direction of increasing galactic longitude ( $\nabla l$ ). This will give us the projection of galactic plane in that region of the sky, which is expected to be the projected direction of local galactic magnetic field. These polarization maps for all the above clouds are reproduced in Figs. 1-10.

When we observe polarization for the stars in a particular cloud, we are not sure whether the observed polarization is introduced by the cloud or it is just the interstellar polarization for that part of the sky or a combination of the two. To ascertain this, we observed nearby regions of two individual clouds, viz. CB3N and CB25N. We notice that, both these regions contain a set of almost unidirectional polarization vectors and the observed degrees of polarizational don't differ much from star to star. This can be considered to be characteristic of interstellar polarization for that part of the sky.

Also we can see both the clouds CB3 and CB25 contain polarization vectors which mostly follow the trend observed in their respective nearby regions CB3N and CB25N. But the small twist in the orientation of polarization vectors in CB3 (in the lower part of the map) may be due to some reasons intrinsic to the cloud. CB25 mostly contain undisturbed polarization vectors.

Clemens et al. (1991) describe some classification scheme for these clouds and divide them into different groups A, B and C. Out of 248 clouds catalogued by CB, most (74%) of the clouds belong to group A, where gas temperatures are cool ( $T < 8.5^{\circ}$ K) and turbulent gas motions are less (characterized by $^{12}\rm CO$ line widths $\Delta V < 2.5~ {\rm km~s}^{-1}$ ). When line widths are broader (> 2.5 km s^-1), we get another set of cool clouds with unusual dynamical activity, these are group C clouds. Under group B we have warm clouds ( $T > 8.5^\circ$ K) but they are less dynamic with narrow line widths. We have observed four clouds CB25, CB246, Cb39 and CB58 from group A and three clouds CB3, Cb54 (comprising two parts) and CB52 from group C (Clemens et al. 1991). Only for one cloud CB62 the group is not known. Keeping these classification in mind we can analyze the observed polarization values for each cloud.

For cloud CB3, the typical polarization values are between 1 - 2% and sometimes even more than 2%. There is not much dispersion among the observed polarization values. However, the polarization vectors do not seem to be aligned in the direction of $\nabla l$ , which is the projection of galactic plane. Except for three or four stars, all the polarization vectors seem to be directed in some common direction. As discussed in Sect. 2. this cloud contains YSO, IRAS point source, further it belongs to group C, where some dynamical activities are expected.

CB25 and CB39 are two clouds, which exhibit the best alignment of their polarization vectors in the direction of $\nabla l$ , among all the clouds we observed. Also the dispersion in PA ( $\theta$ ) values seem to be very small in both the clouds. The alignment is slightly better in CB25 as compared to CB39. Both these clouds belong to A- group. Therefore we can expect, less dynamical activities and turbulences and here we observe better alignment of the grains (or polarization vectors). The cloud CB25, has polarization values typically near 2%, sometimes even exceeding 3%, however these polarization values can be attributed to the interstellar polarization as discussed earlier, with small contribution from the cloud.

For CB39 the polarization vectors are relatively less unidirectional, rather they represent some pattern. The cloud contains YSO, IRAS point sources and CO out flows, so it is definitely more active than CB25.

For CB52 (belonging to group C), the alignment of the polarization vectors appear to be disturbed. The polarization values quite dispersed. Some of the polarization vectors are aligned in the direction of $\nabla l$ . This cloud contains YSO and IRAS point sources.

In CB54, there seems to be some emission nebulosity associated with the cloud and we have made observations on the north and south of this. For the northern part (CB54A) the alignment of the polarization vectors is rather poor, as compared to the southern part (CB54B). However, in the northern part of CB54A, the orientation of polarization vectors seem to follow some circular pattern. This is interesting and need to be studied more carefully. CB54 belongs to the dynamic group (C) and it contains YSO, IRAS point sources and CO out flows. The measured polarization values are generally close to 1% and there is wide dispersion among the direction of polarization vectors.

CB58 (belonging to group A) seems to be an interesting cloud with low to very high (4 - 5%) polarization values and direction of polarization vectors are scattered. This cloud seem to be violating the trend where we observed, group A clouds exhibiting slightly better alignment of the polarization vectors among themselves and also with the direction of $\nabla l$ . This cloud contains YSO alone.

CB62 is the only cloud cloud which is quite above the galactic plane ( ${\rm bII} = 37.58^{\circ}$ ).
Otherwise all the clouds we observed are within the galactic disk ( ${\rm bII} < \pm 10^{\circ}$ please refer Table 1). Also we have no information about the group in which it belongs. Very few stars appear to be polarized in CB62. This is expected as the cloud is well above the galactic plane, so that the polarization caused by interstellar dust will be relatively less. The directions of polarization vectors seem to be scattered, with degree of polarization ranging from very low to above 2%. The polarization vectors do not appear to be aligned with the projected direction of galactic plane ( $\nabla l$ ). If a typical A_v for stars in CB62 is found to be similar to the A_v for stars in the plane, this proves polarization is mostly interstellar in all the other cases (not arising from the cloud itself).

In CB246 (belonging to group A), polarization vectors are poorly aligned amongst themselves and also with the direction of $\nabla l$ . However, if one separately considers the eastern and western regions in the cloud, one can see within these two individual regions the vectors are moderately aligned. This observed feature can be related to some activities in the cloud. However, as seen from Table 1, it does not contain YSO, IRAS point source or CO outflows.

The reason that the more "dynamic cloud'' shows generally poorer alignment with the galactic plane is that these regions tend to be warmer. Warmer regions have been shown to have better grain alignment. So it is possible that only in these clouds polarimetry is tracing the field, which in fact does not align with the galactic plane.

Also to draw a firmer conclusion about the alignments one needs a "control sample'' of "off/nearby'' positions where the projection direction is compared to the plane direction in the same way as for the globules. We have done it in a way for CB3 and CB25. However, we want to do it for all the globules in future.

In order to discuss about the alignment of the field or the lack of it in individual clouds, we have tabulated the average directions of polarization vectors ( $\theta_{\rm average}$ ) and the dispersions in the direction of polarization ( $\sigma_{\theta}$ ) in Table 15. If all the stars have ${{E_{\rm p}} \over{p}} = 0.5$ , the error on the angle ( $E_{\theta}$ ) would be $\sim$ 14 degrees. Hence one can say that a $\sigma _{\theta} < 10$ degrees would mean that the field is very well aligned, whereas a $\sigma _{\theta} \sim 50$ degrees would mean randomly directed polarization vectors (or field). Therefore CB52 represents almost random directions and CB54A & CB58 represent highly dispersed directions of polarization vectors with themselves and the galactic plane.

The disturbance in the polarization directions, that we have mentioned has been discussed extensively by Myers & Goodman (1991). Their analysis includes several clouds and the number distributions of polarization direction have a single maximum, with dispersion 0.2 - 0.4 radians. The observed distribution of polarization was modeled as arising from a magnetic field with uniform and non-uniform parts. The uniform part has an isotropic probability distribution of direction, a Gaussian distribution of amplitudes and N correlation lengths along the line of sight through the cloud (with the estimated upper limit $N_{\rm max} \sim 10$ , based on the cutoff wavelength of hydromagnetic waves).
