Severe damage results if not fully protected, and at tem- peratures above the general tol- erance. Prior to our afternoon forecast of minimum temperature, growers can get an early indication of the minimum to be expected by sub- tracting 20° from the Weather Bureau's forecast minimum for Boston. Their morning forecast is given at 7:40 a. m. Generally the more positive frosts follow when a high is directly over or slightly south and west of this area. Before their arrival at such a position we usually experience a night of cold temperatures accompanied by winds, inland bogs being the ex- ception. The day following often finds winds becoming light and shifting into the southwest in the afternoon. Such a sequence is not an indication of a change to warmer. This "sea breeze" will calm toward sunset and the fol- lowing morning will likely find temperatures at frost levels on the bogs. It was estimated that water damage caused a loss of 50,000 bbls. in the spring frost season of 1964. Periods of threatening frosts continuing from one day to another have not been common in the past decade, and it may be possible that many growers are unaware of the damage that water can do when held over from day to day in the last part of the spring frost sea- son. In a normal year, the risks of damage become increasingly great with the holding over of a frost flood after May 10th. Even though experiences will vary from bog to bog and year to year as to the amount of damage one receives when doing so, it can result in a complete loss of the crop. In that it is necessary to keep the forecasts concise as sent to the telephone distributor and radio stations, I try to include a few more details in using the answering service. This also is limited to the length ,-of message that can be taped on our machine. Joking, of course, but I would like to see t
