Mayhew 1961 Journal 61. July 23 Glamis area, Imperial Co., Calif. If we include the dead animals that have been seen on the road as well, since these have been removed from the population, the counts are 75 animals removed in the past two months (9 dead ones) and 114 animals in 1961 (29 dead animals). This accounts only for those animals we have seen - it doesn't take into account the number that must be killed each week while the gravel trucks are traversing the road. Much of our collecting has been on the week-end when gravel trucks aren't using the road. Therefore, the dead ones have been run over by the few cars that use the road during the summer. We have always found more dead ones on days when the gravel trucks were running. The carcasses never remain on the road more than a couple of days at the very most, so the same relative number probably are killed each week. This may not make a great deal of difference in the entire population, though, since the great majority have been seen at the sides of the road instead of on the pavement.
