I take this time to ask the gentleman from Iowa . the author of this amendment. about this situation: I represent a district of small farmers. The average size of their farms is under 100 acres. and it is the major single industry of the district I represent. The farmers in my district depend on Mexican migrant labor for about 30 percent of our crop. One of the things the farmers of my district have been concerned with is the matter of the regulations and their enforcement. particularly enforcement. May I ask the gentleman from Iowa what is meant by the operation of farm equipment?
