. Cranberries; : the national cranberry magazine. Cranberries. Mass. Cranberry Station and Field Notes by J. RICHARD BEATTIE Extension Cranberry Specialist. Temperatures have been running well above normal for December and January. Should this weather pattern continue through Febru- ary, conditions will be favorable for the growth of scum or algae, as it's called, under the winter flood. Growers are urged by Dr. Franklin to be on the watch for this algae, which appears under the ice or water as a green film over the vines. In fact, it has already been seen on several bogs. The Copper Sulphate Treatment will take care of this problem ef- fectively. Probably the cheapest treatment is to broadcast fine crys- tals on the ice at the rate of 10 lbs. per acre in February and again in March. However, if the ice is gone, place coarse crytals in a burlap bag and tow behind a boat, using approximately 4 lbs. of coarse crystals for each one acre foot of water. Since the al- gae usually has its start near the ditches, be sure that these areas receive special attention. The main point is to treat the bog early and repeat the application if necessary. A word of caution is necessary since copper sulphate is sometimes harmful to fish life. A reasonable period of time should elapse before draining off the win- ter flow into any fish stream or pond after treating for scum. Growers will be interested in a note received recently from Wal- ter Piper, Division of Markets, Boston. Mr. Piper was in charge of the cranberry-apple pie contest that received so much publicity at the Union Agricultural meetings in Worcester. A quote from his note seems in order: "Beneficial results from the cranberry-apple publicity at the Union Agricultural Meeting in Worcester continue to accumulate. Evidence of the widespread pub- licity given these two fruits keeps coming in from many places— some surprisingly distant from Massachusetts. For instance, we have a report of a newspaper story of the big pi
