of the powder charge. There is very little report when fired & little smoke & it can be placed in a trench. Its range is about 300 yards, but it is by no means accurate and a trajector's trajectory table is required showing the charge required for any given range. Walked out in the afternoon to inspect the stables built by units. Jan 17-19 In the trenches - heavily shelled & a good bit of parapet blown in, but not many casualties from the shell fire. Snow falls on 19th but thaws very quickly making the country & trenches worse than ever. Some of the German rocket flares come right over behind our trenches
