Snowmaking corrected
The general mathematical relationship which correlates the variables required to estimate air system capacity should be written as follows:
A=(V) (k)/(t)
where A=air capacity, c.f.m.
V=snow volume, acre-ft.
k=efficiency constant, dimensionless
t=time, hours
The other error involves the fifth sentence in the first paragraph concerning electrical requirements. The correct sentence is as follows: “However, in installations where extremely large power requirements are needed the costs associated with wiring, disconnects, starters, etc. might make it economically advisable to operate at higher voltages.”
I want to commend you on the general content of the magazine. I look forward to its arrival each month.

The disposal problem
We have just received your April issue and read the RESTAURANT feature relating to the disposal of solid wastes in restaurant and cafeteria facilities at ski areas.
I am enclosing literature on a piece of equipment known as the Cruncher, which you may be interested in bringing to the attention of your readers. The Cruncher has a twofold advantage—its economy in original cost and cost of operation, and its efficiency in handling solid wastes.
We have been at Arapahoe Basin Lodge, at Arapahoe Basin ski area, since November 1966, and one of our biggest problems has always been handling solid waste from the cafeteria. In the past, we had bags upon bags of discarded paper goods, plastic ware, tin cans, glass jars and bottles, and what have you. These bags had to be carted away by the local trash disposal service to be dumped at the county dump—at $25 per pick-up, with three to four pick-ups a week. Sometimes the trash truck would not be able to pick up because of snow accumulation, and by the time they could pick up, some of the bags were hopelessly buried until the spring thaw.
Then last fall we purchased a Cruncher. Now the snow is starting to melt, but we do not have any loose trash lying around and the clean-up job behind the lodge this spring will be almost non-existent. Also, all during the winter, we have only had to have one trash pick-up a week, thus reducing our trash collecting expense to one-
