Duckweed

I have a small pond with a few happy fish and an itinerant population of frogs from time to time. For a couple of years, I have had duckweed growing on the surface, and find an almost sensual pleasure in gathering the bright green mini-plants into my hands to form wet clumps to add to my compost bin.

I know how it came to be in my pond. One Mother's Day, my eldest daughter gifted me a bucket of copulating frogs which had a few tiny duckweed plants in the water. I am not complaining; it was and will always be the most memorable and interesting Mother's Day gift that I have ever received, and neither the fish nor the frogs are bothered by the duckweed.

The botanical name for duckweed is Lemna Minuta, and in the right sunny conditions, the mass of plants can double in size every 2-3 days. Domestic ducks, coots, moorhens, turtles and grass carp will eat it. It is possible to buy supplies on Ebay for your pet turtles. If you live nearby, just knock on my door and you are welcome to collect your own, free of charge!

Weeding it with a rake or by hand is the best option if the growth is too profuse. Apparently, if you grow watercress, it will stifle the duckweed. I might try this. I am very fond of watercress.

Chemicals are too toxic for the gardener to use, though there is a product which consists of bacteria( which alter the proportion of nutrients in the water) that is available to purchase. I am not sure that my fish would be in favour of this remedy. Since the duckweed acts as a haven for small water creatures, and control is impossible, I would recommend living with it and learning to appreciate this amazing little plant.

There is an International Lemna Association which is exploring commercial uses for duckweed, including using it in animal feeds, sewage treatment, and to remove toxins from water. There are even videos on the internet to show you how to grow it. Guys! It is not that difficult! All you need is a small pond and some sunshine!

I love to see the frogs poking their faces out of the mass of green weed, looking at me sideways, wearing duckweed on their heads like a tarnished crown. Thank you, Louisa, for that gift!

 

Comments on births in Dublin, Ireland, in 1946

I retrieved a number of items from my parent's house relating to my father's training as a doctor in the 1940's. One of the items was his official record of attendance at births in the Rotunda Hospital, Dublin, dated 1946, which he would have completed as part of his required training before taking his examinations in Obstetrics.

There are 18 cases documented. The information given includes the age of the women, number of previous pregnancies and the occupation of the baby's father. The ages ranged from 22 to 43.The majority of the fathers were described as labourers, reflecting the social background of the catchment area for the Rotunda Hospital at that time. Other occupations noted were taxi drivers, a flour miller, a railway employee and a plumber. Only two out of the 18 had no occupation recorded , and one was recorded as unemployed. It was assumed that the woman would not have an occupation.

Multiple pregnancies were common. One woman aged 39 years was delivering her eleventh child, and half of the women had more than 5 children.

I was particularly interested to see that the birth weights of the babies were healthy. All were recorded as between 6lbs 11 oz. and 8 lbs in weight, with only two weighing below 7lbs.

As in the UK, rationing of butter, margarine, bread, flour and fuel for cooking was still enforced in 1946, and not lifted until 1949. A National Nutrition Survey in Ireland took place between 1946-1948 and interestingly found that most of the population were adequately fed, even in the cities, due to the strong influence of dairy farming. There was also a public health system in place for mothers during the 1940's ensuring free maternity care for all. These facts may explain, to some extent, the healthy birth weights.
