April 6th, 1911. 



4 p.m. Snow-cloud over the sky all day. CJranular snow falling slightly until 2 p.m. At 

 2 p.m. the sky to the S.E. was clear, but between 2 and 4 p.m. it clouded over again, a 

 southerly breeze blew about force 2, and heavy flake snow began to fall about 3 p.m. 



The flakes consist of rods, grains, and little plain six-rayed stars of diameter about 

 -fa inch. The snow during the whole of this storm has been of decidedly smaller grain 

 than that which has fallen before when the grains have been generally about i inch in 

 diameter and the plain stars the same while the compound stars were from | to j* inch 

 in diameter. This time the grains are about the size of a pin's head. 



The barometer started falling between 12 noon and 2 p.m., and the temperature is 

 rising a little. 



8 p.m. Weather cleared and the snow ceased at 6 o'clock. It was thick again and heavy 

 snow falling at 8 o'clock. Thermometer steady at plus 13 F. Barometer falling all day
