This is in response to the letter by Philip Newton {March 16} on the picketing by the Uniformed Division of the Secret Service. Mr. Newton believes that if any pay raise is given, it should go to the Park Police.

I have been a member of the Uniformed Division of the Secret Service for the past 12 1/2 years. I have worked in all branches of the Uniformed Division, but I have yet to work in a bulletproof booth with climate-control. I have worked in booths with a heater that does not work in the winter and an air conditioner that does not work in the summer.

I have also stood in front of unoccupied embassies at 2 a.m. on Christmas day, on my wedding anniversary and while it was either 20 degrees or 90 degrees, depending on the time of the year.

We also have been required to travel with the president and vice president, working 10- to 20-hour days, only to return so we may work our next tour of duty.

I currently work in a unit that answers requests by the Park Police for assistance on a 24-hour basis. This is because their officers are on call, and it's easier to use us than to bring in their own people. We do this out of professional courtesy.

Mr. Newton should realize that although the picketing may have been directed at the Uniformed Division, what we may get can only help the Park Police. When was the last time the Park Police got a pay raise?

Mr. Newton and the president of the Police Association should remember that one day the Park Police may need our assistance. ROBERT HOGAN Gambrills, Md.
