r than introduced species. The wind, rain and wave action moves sand, removes vegetation and it cleans out debris from channels and rivers. In general it resets habitats to an earlier successional stage. Birds needing such habitat include Wilson’s and Piping Plover, American Oystercatcher and Least Terns and Black Skimmers. After several years of without storms the habitat degrades for the above species and they must move on or the population declines. In Connecticut we have gone many years without a hurricane and its cleansing effects. One can see the consequences at many of our birding spots (if you’ve been around for a while), Long Beach Stratford, Milford Pt. Milford, Sandy Pt. West Haven Griswold Pt. Old Lyme. The negative reputation of hurricanes is derived from its conflict with humans. The Atlantic coast in reality is a dynamic system of mobile barrier beaches, channels, and salt marshes. Humans in an attempt to utilize them set about to stabilize this fluid system. Breakwaters and jetties are built, channels dredged, and sand filled in all in attempt to stop time and tide. The loss of life and property is a consequence of this attempt. In Fairfield I know of beach houses with all pilings under water at high tide. Penfield Reef once was a bar where colonials grazed cattle. I don’t know how many times sand was dumped in West Haven to replace that which was eroded away. At one time beach houses ran the length of Long beach from Oak Bluff Ave. to Pleasure Beach. A hurricane removed the houses and created a channel into the marsh, you can see this on old maps. In the early sixties the Army Corps of Engineers closed the channel and built the jetties. If houses weren’t built in exposed locations then hurricanes would not be such a problem. Hurricanes may actually provide opportunities to create more coastal open space as the government gets tired of subsidizing flood insurance. Given all the above, another benefit of hurricanes is the birds it brings. Hurricanes may bring exotic birds, but there is no certainty as to what gets brought in. The path of the hurricane and time of year determines what birds get picked up. Where it makes landfall affects distribution. Sometimes we get exotic pelagics, sometimes an increased abundance of regular birds, and sometime just a lot of late records. Dennis Varza Fairfield

, cfg=trans_cfg) [...] returns with: python: ../src/pjsua-lib/pjsua_core.c:2010: pjsua_transport_get_info: Assertion `!"Unsupported transport"' failed. Replacing pj.TransportType.TLS with pj.TransportType.UDP or pj.TransportType.TCP it works well. I also tried to establish the TLS connection by using C and it worked too. How can I solve this problem in python? Thanks in advance. Regards, Sebastian

one a lot of shaft work on fishboats suggested that I replace the ball bearing with a babbit pillow block bearing which has two split halves. The babbit bearing allows fore and ant shaft movement and can be replaced without removing the shaft. Some fore and aft shaft movement occurs when shifting between forward and reverse.
