Subject: EQUIPMENT & SUPPLIES: Instrumentation--New suspended 
         sediment water-quality samplers 

This is to advise you of the availability of two new 
suspended-sediment samplers. These new samplers are welcome 
additions to the existing U.S. series of suspended-sediment 
samplers because they will accommodate either the standard 
pint bottle or a commercially available l-quart bottle.

The USD-74 sampler is a modified D-49 sampler made of bronze. 
It weighs approximately 62 pounds and will take a l-pint or 
l-quart bottle.

The USD-74Al sampler is a modified D-49 sampler made of 
aluminum. It weighs approximately 30 pounds and will take a 
l-pint or l-quart bottle. This sampler can be used on a 
handline if necessary.

Both samplers are available in the trace-metal version for 
water-quality sampling. For information on price and delivery 
time contact the Sedimentation Project, St. Anthony Falls, 
Minneapolis, Minnesota. The Sedimentation Project also can 
furnish the quart bottles; however, you may find that they 
are available from a local distributor (Owens-Illinois No. 
6762).
